    The error indicates a toner sensor problem. Have you already tried swapping the toner? Remove cartridge and ensure toner sensor in printer is positioned correctly. You may also try replacing the toner sensor cable or the system board.

  1. If the printer is currently displaying a 900 RIP Software error, power off the printer and leave it powered off for 20 seconds or more. Doing this will clear the printer's memory.
  2. While the printer is off, clear any pending print jobs from the computer or the network queue. This will prevent any corrupted print jobs from being sent to the printer again when it is powered back on.
  3. Power the printer back on.
  4. If the printer goes to the Ready status, try printing again.
  5. If the 900 RIP Software error returns when the printer is powered up or when you try to print, there is a problem with either the printer, the communication cable connecting the printer to the computer, or with the print job itself. Follow the directions below to check each of these components.
    • If the error appears every time you power on the printer, regardless of whether you send a print job or not, the likely source of the problem is the printer or an option installed on the printer.
    • If the error appears only when you send print jobs to the printer, the likely source of the problem is the computer, a setting on the printer, or one of the communication cables.

SOURCE: lexmark t644 error code 917.00

This error indicates that there is a charging problem with the transfer roller. You could start by cleaning the contacts for the transfer roller (power off printer first). The transfer roller is the black foam-like roller under the toner cartridge. Handle it with paper because the oils on your hand could damage it. To remove it, just pry under the far left side with a screwdriver. Lift and pull to the left to remove. If this does not fix it, then you have a more serious problem. It could be one of the arms or the HVPS.

HORIZONTAL LINES ACROSS T644 PRINTER AND 930.00 ERROR CODE


Hello,

The error code 930.00 indicates a problem in the laser print head section of the printer. This will cause error in the printouts like you are having. This type of problem is not user serviceable and will require an authorized service dealer to obtain and install the printhead assembly. This is directly from page 2-24 of the service manual.

Have a look in the preference settings of the printer driver and check the paper type. If this is set to color letter you'll have to set the traysettings to the same type of paper. Best is to set both setting to normal paper.
