Reset pc kit life on xs463de

With printer off, simply move the carriage to the center
Remove all the cartridges
at the center of the carriage you should see a button that if pressed pulls out a kind of lever, now you can take your pinthead off!

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.

Here is an excerpt I found from the W840 user manual. Looks like you need to change the photoconductor kit. Here is the link for the user manual: images.lexmark.com/publications/pdfs/w840/eng/ug.pdf
To ensure print quality and to avoid damage to the printer, the printer stops operating after the photoconductor kit has reached approximately 60,000 pages (Letter/A4). The message 84 Replace PC Unit is displayed when the printer reaches this point. If the Toner Alarm setting is set to Single or Continuous (default is Off), the printer automatically notifies you before the photoconductor reaches this point and displays the message 84 PC Unit Life Warning. To avoid having the printer stop operating, replace the photoconductor kit when you first receive the 84 PC Unit Life Warning message. Once the photoconductor kit has been replaced, normal printer operation resumes

To reset the PC page count, while the printer is on, open front cover then press the cancel button.
NOTE: The photoconductor page count should be reset only when a brand-new photoconductor kit is installed. Resetting the page count without replacing the photoconductor kit could cause the photoconductor to operate beyond its intended life and thus create print quality issues.

84 PC Life Exhausted indicates that the photoconductor unit has reached its functional life. The photoconductor kit will need to be replaced. The printer will not function so long as the Exhausted message remains on the display. The only way to clear the message is to install a new photoconductor. After replacing the photoconductor unit, you need to manually reset the pc page counter as well. Thank you for choosing Lexmark.

The light pattern indicates that the photoconductor kit has reached the end of its useful life. Replace the photoconductor kit then reset the photoconductor page counter. Thanks for choosing Lexmark.
