Recommended action Follow the instructions below to help solve the issue: Turn the printer off and allow a few minutes for printer to cool. Turn on the printer, following initialization re-send the file that generated the error. If the error re-appears, re-create the file and try printing again. If the file is PostScript, check to see if it is binary. If the file is binary, use AppleTalk to send the file to the printer. If AppleTalk is not being used to send the binary file to the printer, change the printer's internal PostScript settings to Binary (Set-up menu, PS settings, Encoding, Binary ). If the error message persistss, check for a new release of the driver. Click here to download HP drivers and/or software . (The link is http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?locale=en_US System error 64:04 Explanation Firmware error (USB port). Recommended action Follow the instructions below to help solve the issue: Turn the printer off and allow a few minutes for printer to cool. Turn on the printer, following initialization re-send the file that generated the error. If the error re-appears, upgrade the printer's firmware (if upgrade is available). Click here for instructions on upgrading the printer's firmware . System error 65:03 Explanation Generic input/output port communication problem. Recommended action If error 65:03 occurs when trying to access the printers front panel IO menu, upgrade the firmware to v. A.02.08, which fixes the issue. Click here to download firmware from the HP business support Web site . (The link is http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?locale=en_US.) If the error occurs during printing, follow the instructions below: Turn the printer off and allow a few minutes for printer to cool. Turn on the printer, following initialization re-send the file that generated the error. If the error re-appears, re-create the file and try printing again. If the file is PostScript, check to see if it is binary. If the file is binary, use AppleTalk to send the file to the printer. If AppleTalk is not being used to send the binary file to the printer, change the printer's internal PostScript settings to Binary (Set-up menu, PS settings, Encoding, Binary ). If the error occurred while trying to access the IO Menu, then there is a solution : just upgrade to firmware A.02.08 , which in fact solves this problem. The root cause was the combination of hostname (printer name) and domain name exceeding 31 characters. The maximum length has been extended to 255 characters for an IP address and to 47 for an IPX address. If the error message persistss, check for a new release of the driver and/or upgrade the printer's firmware. Click here to download HP drivers and/or printer firmware .

Turn the printer on and attempt to verify functionality. Click here to contact HP support if the problem persists . System error 86:01 Explanation Carriage-Axis shutdown. Recommended action If this error code appeared but was NOT caused by a paper jam, then try the following: Maybe there is too much friction on the Slider Rod. Enter the Printer Information utility and check the Scan-Axis usage. If the percentage is close to 100%, then lubricate the Slider Rod using the HP synthetic lubricant specific to the printer. Service may be required to replace the Carriage Motor and/or related components. Maybe the Carriage is bumping into the Service Station. If the carriage is stuck at the right hand side of the Printer and cannot be moved out to the center of the Print Platen, likely it is because the Service Station cannot uncap the Printheads. Do not try to pull on the body of the Carriage. That can damage the Carriage or the Service Station or both. Service may be required to adjust or replace the Service Station and/or related components. There may be debris or an object in the path of the Carriage.

Remove the accessory card cover from the back of the printer (right-side of printer looking from the back). Figure 1: Removing the card cover With a flat end screwdriver, unscrew the two screws that attach the Formatter card, HP-GL/2 accessory card, or the Jetdirect print server to the Electronics module. Figure 2: Screws securing Formatter card, HP-GL/2 card, or Jetdirect print server   NOTE: The 500 and 800 series printers have different cards (Formatter, HP-GL/2 accessory, or Jetdirect print server) that may or may not be installed in the printer (optional with some printer models). The preferred slot for the Formatter card and the HP-GL/2 accessory card first slot in the printer (outside slot). The preferred slot for the Jetdirect print server (optional, depending on model) is the inside slot.   NOTE: The Formatter card, HP-GL/2 accessory card and the Jetdirect print server will work in any slot, as the EIO slots are interchangeable. Therefore, the cards can be swapped with a different slot for additional troubleshooting purposes. Remove the Formatter card, HP-GL/2 accessory card, or the Jetdirect print server as needed. Figure 3: Removing Formatter, HP-GL/2, or Jetdirect print server Reinstall the applicable card into the necessary slot. Using the flat ended screwdriver, gently tighten the screws until the card is secure. CAUTION: Do not overtighten the screws. Reinstall the accessory card cover.
