SOURCE: Wiper blade

When you say wiper blade, do you mean the one in the cartridge? There's also a cleaning wand in the top of the fuser.

Hi,

This is a call for service message generally requiring professional repair.

There are generally only four reasons:

No power, Check fan power leads as one may have slipped off it's fitting

Jammed: Either too dirty or a shred of paper may be blocking the blades, pull free and clean off with compressed gas(no more than 25ft/lbs)

Dead fan: Call a repair man or call lexmark and give them the exact code,they will identify the fan and can sell you the part.

Dead controller board: as with above call a repair man or lexmark with code and order spare part.

The only bad news other than you may need a repairman, if you order the fan or controller board it may be the other and no way to know ahead in some cases.

The good news, if you're still under warranty, lexmark has good repairmen and fast response times in most areas.

Either way, Hope this helps FixYa,


Chris

    SOURCE: where to change the setting of a lexmark t642

    Hi,
    The setting should be on the driver. Once you are ready to print a document just select print then printer options and you should see the option of two sided printing and select the long edge or short edge. If you want to know where in the printer menus is the option, then go to the printer menus then select Finishing Menu then Duplex and just select ON. that should activate the duplex option.

    How do I change toner to my Lexmark T642. I can't find an instruction in the manual. The instruction in the toner cartridge is ununderstandable. I can't find what to press to remove the old cartridge....


    Good day! Error 1203 means that there is a communication failure between one of the cartridges and the pritner. Try these procedures to help you resolve the problem:
    1. Power off the All-In-One (AIO) and remove the power supply from the back of the unit. Wait 30 seconds, then reinsert the power supply and power the AIO on. If no go,
    2. Power off the AIO and remove the power supply from the back of the unit. Open the top cover of the AIO. Using the carrier belt, gently move the cartridge carrier to the middle of the unit. Remove both cartridges from the AIO. Close the top cover, reinsert the power supply, and power the All-In-One (AIO) on. If the error pops up, there is a hardware problem with the printer.
    3. Power off the AIO and remove the power supply from the back of the unit. Open the top cover of the AIO. Using the carrier belt, gently move the cartridge carrier to the middle of the unit. Insert the color cartridge. Close the top cover, reinsert the power supply, and power the AIO on. If the error still pops up, continue cleaning or replace the cartridge. If no error,
    4. Do step #3 again for the black cartridge. If error pops up, continue cleaning or replace black cartridge. If no error, print a test page.
    Hope this helps.

    We can't get the lexmark t642 printer to work at home


    The printer is not hooked up to the wireless network. It will work if hooked up with an ethernet (hard wire) cable. Anyway, it is a royal PIA to set up - let him take care of it.
