The exceptions are page count and display Language. HP LaserJet 4P Printer - this reset returns all Printing, PCL, Job, Config, Parallel, Serial and installed personality menu settings to factory default configuration. The exceptions are page count and display language. This reset may need to be done when an MIO card is installed. Use with caution; always do a self-test before the cold reset to maintain a record of the printer's current settings. In a shared environment, this reset should only be performed by the system administrator. To do a cold reset, hold down the [online] key while switching the printer on until 08 Cold Reset appears in the printer's display.
68 Cold Reset	IIISi	The printer's non-volatile memory is new, or the battery is dead. The printer returns all Printing and Configuration menu selections to factory default. If the printer is set up as a PostScript printer, the 68 reset will return it to PCL status. If the message always appears when the printer is turned on, the printer will still operate, but it should be serviced to correct the problem.

Press and hold [Continue/Reset] until 07 Reset appears to confirm the selections (temporary macros and temporary fonts will be deleted) or, press [Continue/Reset] or [Online] (no changes to any menu selections will be made.
11 Paper Out	LaserJet, Plus, 500 Plus, II	Paper tray is empty. If there is paper in the tray and the printer still displays 11, verify the tray is all the way in. If the message persists, consult service.
12 Printer Open	II, IID, III, IIID, IIISI, 4, 4M, 4Plus, 4Mplus, 4Si, 4Si MX	The printer's top cover is not correctly closed, or the toner cartridge is not correctly installed. Verify the toner cartridge is fully seated and close the printer firmly. Plugging a 220V model printer into a 120V power source can also result in this message. If this message persists, a repair may be required.
12 Printer Open Or No EP	IIP, IIP Plus, IIIP, 4P, 4MP	The printer is not closed properly, the toner cartridge is missing, broken, or defective, or the cooling fan is not working. Plugging a 220V model printer into a 120V power source can also result in this message. Ensure the printer is firmly closed. If the message persists, consult service.
13 Paper Jam	II, IIP, IIIP, IID, IIP+, IIID	Remove jammed paper. The top must be opened and closed (the front on the IIP, IIP+, IIIP) to clear the message. Double check the duplexing paper path on the IID and IIID (left side door). If the message persists, there may be a malfunctioning paper path sensor and service would be needed.
13.X Paper Jam 1 internal 2 input 3 duplex 4 output	IIISi, 4Si, 4Si MX	Paper is jammed somewhere along the paper path. The value that follows the "13" in the message window will indicate in which part of the paper path the paper is jammed. Also, the paper jam sensor at the rear of the fusing assembly may have become stuck. Check the optional duplexing paper path if the duplexer has been installed.
13 Paper Jam	IID, IIID	Paper jams can occur in these printers when using the "automatic manual feed" as opposed to explicitly putting the printer in manual feed mode. The use of "automatic manual feed" is not a supported feature, nor is it a suggested procedure. This procedure is known to cause problems, particularly when using the lower cassette as the manual feed slot because it is more difficult to align the paper properly when it is pulled in from the lower input slot. Paper is the only print media that should be fed from the lower input slot and other types of media may not only cause jamming, but also permanent printer damage.
13 Paper Jam	HP LaserJet 4, 4M, 4Plus, 4Mplus, Printers	Paper is jammed in the paper path or the paper jam sensor at the rear of the fusing assembly may be stuck, causing a false paper jam warning. Remove jammed paper. While clearing paper jams the top cover or rear cover must be opened and closed again before pressing Continue or online to resume. Check that the rear cover is closed; an open rear cover may cause a paper jam. If no paper jam is found, check locations shown in the user's manual.
	4P, 4MP	Paper is jammed in the top or rear of the printer. Clear jam and press Continue or Online to resume printing. To prevent further jams, verify the rear door is closed securely. A false paper jam message will occur if the printer's back door is open. If message persists, the printer could have a defective paper jam sensor and service would be required.
14 No EP Cart 14 No Toner Cart	II, IID, III, IIID, IIISi, 4, 4M, 4Plus, 4Mplus	There is no toner cartridge in the printer, or this message indicates the possibility of a broken or damaged toner cartridge. Turn the printer off and back on. If the message returns replace toner cartridge. After replacing cartridge if the message still occurs consult service.
15 Engine Test	Not all printers have this option.	Engine Test with a single sheet of vertical line printout also known as a "skewing" test.
16 Toner Low	II, IID, III, IIID, 4, 4M, 4Plus, 4Mplus	Toner cartridge is low on toner. The message may also indicate the EP cartridge is not making good contact with the printer's internal circuitry. Shake and re-install the toner cartridge. Replace the toner cartridge. If the message persists, consult service. On the LaserJet 4, 4M, 4Plus and 4MPlus Printers if Toner Low=On (Config menu), this message will remain in the display until the toner cartridge is changed. If Toner Low=Off this message will disappear by pressing Continue.
16 Toner Low 1 16 Toner Low 2 16 Toner Low 3	IIISi, 4Si, 4Si MX	Toner Low 1 indicates the 8000 page toner cartridge is approximately 200 pages from depletion. Toner Low 2 and Toner Low 3 are indications of further depletion with Toner Low 3 indicating a nearly illegible page. Replace the toner cartridge.
17 Mem Config	IIIP, III, IIID, IIISi	A status message by the printer indicating it is re-configuring internal and expanded memory for page protection. If the you are using an optional I/O board, you may lose the optional setting in the configuration menu. If this occurs after page protection is turned on, power cycle the printer (off and on) and reselect the optional I/O in the Configuration Menu. In some cases, you may have to take the optional board out, set page protection on, then install the optional board.
18 Skip Self-test	III, IIID, IIISi	A Status message indicating that the "minus" key was held down while powering up the printer. If the printer is stuck in this mode, the minus key is probably stuck. Turn the printer off, choose the minus key, and turn the printer back on.
18 Aux I/O Init	4, 4M	The modular I/O card is initializing. This message will automatically disappear after the card is initialized (in less than 60 seconds, depending on the card). No action required.
18 Aux I/O Nt Rdy	4, 4M	The modular I/O (MIO) card is not ready. Refer to the MIO card's documentation. The printer will continue to display this message until the problem with the card is corrected or the card is removed. Always turn off and unplug the printer when removing I/0 cards. Pressing Continue will not clear the display.
18 MIO INIT	4Plus, 4Mplus	The MIO card is initializing. This is a status message; during initialization the MIO is not active, since the printer supports I/O switching, the printer remains on line. No action required, display will clear automatically (this may take up to a minute, depending on the card).
18 MIO Not Ready	4Plus, 4Mplus	The MIO card is not ready. The serial and Bi-Tronics parallel ports will continue to operate normally. SHIFT and Continue will not clear the display. To clear the display, switch the printer Off, remove the card, and switch the printer On. See MIO documentation for troubleshooting.
18 Upper MIO 18 Lower MIO	4Si	The upper MIO card is initializing. During initialization the MIO is not active, but since the printer supports I/O switching, the printer remains on line and displays this status message. No action required. Display clears automatically (this can take up to a minute, depending upon the card.
19 Add Memory	IIP, IIP Plus	This message appears if the PCL 5 Cartridge is installed without adding optional memory.
20 Error	II, IIP, IIP+, IID	The printer received more data (soft fonts, macros or graphics) than it can fit into its internal memory. Press Continue to resume printing. Purchase additional printer memory or reduce the amount of data. Data can be reduced by using fewer soft fonts and macros, smaller graphics, and a lower resolution. A repair is Not required.
20 Mem Overflow	IIIP, III, IIID, IIISI, 4, 4M, 4Plus, 4Mplus, 4Si, 4Si MX, 4P, 4MP	The printer received more data from the computer than can fit in its available user memory. You may have tried to transfer too many macros or soft fonts, or graphics that were too complex. Press SHIFT and Continue to print the transferred data (data loss may result), then simplify the print job or install additional memory.
21 Error	IIP, IIP+, II, IID	The printer is unable to process very complex data fast enough for the print engine. Multiple addressing of single pixels, too many different fonts or characters in a document or too many cursor position addresses per document will cause this error. Press Continue to resume printing. Repair is not required. Workarounds: 1. Reduce the document's complexity by using fewer fonts and removing bolding, shading, or underlining. 2. Reduce the document's graphics resolution.
21 Print Overrun	IIIP, III, IIID, IIISI, 4, 4M, 4Plus, 4Mplus, 4Si, 4Si MX, 4P, 4MP	Complex data (rules, graphics, dense text) have caused the printer's page formatting process to "fall behind" the printing process. For the 4 family this problem is also caused by printing too many typefaces at 600 dpi, or by printing a PostScript job at 600 dpi using only the printers base memory. Workarounds: 1. Reduce the document's complexity by using fewer fonts and removing bolding, shading, or underlining. 2. Reduce the document's graphics resolution. 3. Select the printer's Page Protect option (Letter, A4, Legal). The following amounts of optional printer memory are required to use the "Page Protect" feature: HP LaserJet III Printer FamilyRequires 2 MB to use page protect at Letter, A4 or Legal sizes.HP LaserJet 4 Printer Family Paper Size 300 dpi 600 dpi LTR/A4 2 MB 6 MB LGL 3 MB 6 MB
22 Error 22 I/O CNFIG ERROR	IIP, IIP+, II, IID, III, IIID, IIISI, IIIP	Serial buffer overflow error. The host computer did not receive, or ignored, the printer's request to suspend the flow of data causing the printer's buffer to overflow. Press Continue to clear the error message. Verify that the proper printer cable is being used and that both ends of the cable are tightly connected. If the error appears on the printer at bootup, check to see if the printers serial cable is plugged into the computer's parallel port. If running parallel, the cause could be a bad cable or printer interface. If the error appears only after data is sent, there may be incompatible handshaking protocol; for example, XON/XOFF, or DTR. By default, the printer lowers the DTR polarity and sends XOFF (DC3) to suspend the flow of data. DTR is raised and XON (DC1) sent to resume the flow.
22 Error	4, 4M, 4P, 4MP	The Serial or Parallel (bi-tronics) interface is improperly configured or there is a communication issue. Press Continue to clear the error. Some data may be lost. If on a network contact the network administrator. There may be a problem with the network interface. If the error continues after troubleshooting contact your HP dealer or Service representative. Parallel Communication 1. Defective parallel cable or cable that is over the supported 10 foot length. 2. Verify the cable connections are secure at both ends. Disconnect and reconnect even if they look secure.3. Set High Speed to No and Advanced Functions to "OFF" in the Parallel Menu on the front panel of the printer.4. If using Novell network v. 3.11 and a version of PServer before 1.22. Upgrade to at least PServer v.1.22 and change the "Use Interrupts" setting in the Print Server Information section of the Novell PConsole utility to No. Serial Communication: 1. Serial cable plugged into the parallel port on the PC (error 22 message will appear when the printer is turned on). 2. Defective serial cable or cable that is over the supported length. 3. Verify the cable connections are secure at both ends. Disconnect and reconnect even if they look secure. 4. Not using correct hardware handshaking (XON/XOFF or DTR).
22 SER I/O Error 22 PAR I/O Error 22 MIO I/O Error	4Plus, 4Mplus	SER=Serial interface, PAR=Parallel interface MIO=I/O card. For serial or parallel configuration, the computer and printer are not communicating because of improper signal protocols. Parallel Configuration: May mean a loose, cable connection,or a bad or poor quality cable. Set High Speed to No and Advanced Functions to"OFF" in the Parallel Menu on the front panel of the printer. Serial Configuration: 1. Wrong pacing option may have been selected. The HP LaserJet printer uses XON/XOFF and DTR/DSR signal protocols rather than ETX/ACK protocol. 2. If an error 22 is encountered with the HP LaserJet 4 Plus Printer in a UNIX (R) environment Robust XON/XOFF may need to be turned off. MIO Configuration: 1. This is an I/O buffer overrun error. If you are using an I/O card other than the serial/Bi-Tronics Parallel I/O supplied with the printer, see the manual for that device or contact your dealer. If on a network, contact the network administrator.
23 I/O NOT READY	IIISi	The I/O card is not able to accept data. Print a self-test for more information. If an optional I/O interface is installed, refer to that product's documentation or contact the vendor.
25 PCL MEM FULL 25 PS MEM FULL	4Si	The PCL or PostScript personality memory environment area is full. To continue printing, press Continue; however some data is lost. To prevent reoccurrence, reserve more memory for this environment area.
30 PS ERROR XX	IIISi	A PostScript-specific error has occurred. Refer to the User's Manual for a listing. Most of these messages are eliminated if AUTO CONT=ON. Note: When AUTO CONT=ON the printer will continue to receive, but not process, data until it receives a valid end of job command
