Lexmark x746 ,reset module transfer after replace new module?

Before trying to replace the switch ,are any lights flashing ? 2hi , 4lo, 4hi etc... Do you know which transfer case yours has ?
Transfer Case - BW 4482-NR4
Transfer Case - NVG 246-NP8
How many buttons ?
The BW 4482 transfer case features a 3-button shift control switch located on the instrument panel.
The NVG 246 EAU transfer case features a 4 button shift control switch located on the instrument panel
Before you replace the switch and finding out that it isn't the problem . The switch is a low voltage input to the tansfer case shift control module (A COMPUTER ) Could have diagnostic trouble codes stored .
DTC B0790
DTC B2725
DTC C0306
DTC C0327
DTC C0329
DTC C0359
DTC C0550
Auto part stores can not read these codes .

The BW 4482 transfer case features a 3-button shift control switch located on the instrument panel. When the vehicle has the ignition key in the RUN position, the transfer case shift control module starts monitoring the transfer case shift control switch to determine if the driver desires a new mode/range position. At a single press of the transfer case shift control switch, the lamp of the new desired position will begin flashing to inform the driver that the transfer case shift control module has received the request for a new mode/range position. The lamp will continue to flash until all shifting criteria have been met and the new mode/range position has been reached, or has been engaged. Once the new mode/range position is fully active, the switch indicator lamp for the new position will remain ON constantly. In addition, the switch includes a VSES request button which sends a voltage signal to the transfer case shift control module. The transfer case shift control module in turn sends a request via the class 2 data bus to the ABS control module which controls the VSES system.

The NVG 246 EAU transfer case features a 4 button shift control switch located on the instrument panel. When the ignition key is in the RUN position, the transfer case shift control module monitors the transfer case shift control switch to determine if the driver desires a new mode/range position. At a single press of the transfer case shift control switch, the lamp of the new desired position will begin flashing to inform the driver that the transfer case shift control module has received the request for a new mode/range position. The lamp will continue to flash until all shifting criteria has been met and the new mode/range position has been reached, or has been engaged. Once the new mode/range position is fully active, the switch indicator lamp for the new position will remain ON constantly.
DTC B2725
Circuit Description
The range/mode switch circuit consists of 5 modes. The transfer case shift control module supplies 5 volts to the switch through the 5 volt reference circuit. The current travel through the resistor of the currently active mode. The current is then returned to the transfer case shift control module through the switch signal circuit.
The transfer case shift control module constantly monitors this signal voltage to determine the condition of the mode switch circuit.
When each of the modes are selected they complete a circuit through their own specific resistor. The transfer case shift control module continuously monitors the switch input to determine whether the Neutral, AWD, 2HI, 4HI, or 4LO mode was selected by the driver.

You may want to take this to a repair shop .

This means that the photoconductor has reached the end of life; on other printers, this is called the drum. It transfers the toner onto the page during printing so that it will fuse to the paper. The replacement is $70 from Lexmark: http://www.lexmark.com/US/en/view/Ink/Toner%20&%20Supplies/X340,-X342-Photoconductor-Kit/catId=cat170003-category&prodId=3599-product . The replacement should last about 30000 pages.

To replace the unit after you get a replacement, open the front cover and pull out the print cartridge assembly by the handle. Put the assembly on a flat surface. Remove the toner cartridge by pressing the button on the assembly and pulling on the handle. Open the new photoconductor kit and snap the toner cartridge into place on it. Then slide the new assembly into the printer. The steps are shown here: http://support.lexmark.com/index?page=answerlink&userlocale=en_US&segment=SUPPORT&locale=en&url=http%3A%2F%2Fsupport.lexmark.com%2Findex%3Fpage%3Dcontent%26id%3DSO4365%26actp%3Dsearch%26viewlocale%3Den_US&productCode=&answerid=16777217&searchid=1397780403561 .

After installing this, you need to reset the photoconductor counter.
With the printer on, open the front cover and press and hold Stop for 5+ seconds. When you see Resetting PC Counter release the Stop button. Close the front cover when prompted to do so.

If this doesn't clear the error, try powering off the printer for 10 seconds. Otherwise, try unplugging the printer for a minute to reset the internal memory. If the unit still doesn't reset the counter, it may need service. Contact Lexmark.

I hope this helps.

THANKS & Keep Using fixya

The laser module is dirt. Disassemble laser module and clean it with cloth and alcohol.

Please try to check if the transfer belt is properly installed. Turn off the printer for at least about 30 seconds.
If you need further assistance please contact Lexmark Technical Support Center.

Contact Lexmark technical support (printer under warranty) or local authorized service provider for further assistance. Thanks.

84 TRANSFER BELT EXHAUSTED indicates that the transfer belt is exhausted and must be replaced. A new transfer belt must be installed to clear this error message. For assistance, you can contact Lexmark technical support or your authorized service provider. Thank you for choosing Lexmark.

The transfer belt is located inisde the printer and is what moves the paper back out the printer. You will need to open the back cover of the unit then you will lift the top part of the printer off. This will expose the transfer belt. There is a bracket holding the transfer belt with two screws that will need to be removed. Then two more screws that are holding the belt assembly in place. Once those are removed then you can slide out the transfer belt assembly. The new replacement transfer belt assembly will slide back in replacing the old one. Then repeat the steps opposite to install. Then remove the four spacers on the new belt(on each corner). Then you will reset the counter for the belt and will need to run the printer alignment settings.

What is new to you might not be so new. Sometimes these things can sit on a shelf for months and you buy it not knowing how long it has been there in that store. Being that the belt is possible plastic it wears even if its not being used then it gets old and cracks now you have to have it replaced. Your best bet is to always check to see how long the equipment have been sitting on the shelf before you buy it.

how do you reset the transfer belt of a Lexmark C522 colourlaserjet.

Thanks
