*Optional, unless determined to be otherwise during the troubleshooting process

50.x errors are related to a number of causes and have symptoms that are better defined by the number following the 50. For example, low fuser temperature (error 50.1), fuser warm up error (error 50.2), high fuser temperature (error 50.3), line voltage error (error 50.4 - not fuser-related), inconsistent fuser error (error 50.5).

CAUTION:Error 50.4 is NOT fuser-related. Treat it as a line-voltage error.

To fix the 50.1, 50.2, 50.3 and 50.5 errors

Verify the power source for the printer

Remove and reseat the fuser.

NOTE: When removing the fuser, the plastic cover can come off with the fuser remaining in the printer.

NOTE: If the printer has been moved or bumped, a bad connection can occur between the fuser and the printer. Reseating the fuser can correct this issue.

Replace the fuser, if:

The 50.x error continues and printer maintenance is due, or

The fuser connector resistance is out of specification when measuring the resistance between fuser connectors J132-1 and J132-2

A 50.4 error is not the issue, or

To fix the 50.4 error

Verify the power source

Verify the line voltage to the printer

Reseat the fuser

NOTE: If the printer has been moved or bumped, a bad connection can occur between the fuser and the printer. Reseating the fuser can correct this issue.

Replace the Engine Controller Board

Verifying the power source for the printer

Verify that the printer is plugged directly into a wall outlet, not to an Uninterruptible Power Supply (UPS) or to a power strip.

If the printer is plugged directly into a wall outlet, turn the printer off, unplugging it for at least twenty minutes, before turning it back on. (This is only necessary if this step has not already been done during previous troubleshooting procedures)

NOTE: Unplugging the printer allows it to discharge all power sources within the printer.

Plug the printer into a different outlet and/or a different electrical circuit.

If the message returns, remove the IR pod accessory (if installed) and turn off the printer for at least twenty minutes, prior to turning the printer back on.

Determining if printer maintenance is due

Printer maintenance is due after 200,000 pages. Verify page count using one of two methods:

Print a configuration page, or

Use the printer Service Mode if unable to print.

Printing a configuration page

NOTE: The information in a configuration page is also necessary to reconfigure the printer after replacing the formatter.

To print a configuration page, perform the following steps.

Press the MENU rocker key until Information menu appears on the printer display.

Press the ITEM rocker key until Print configuration appears on the printer display.

Press the SELECT button to print a configuration page.

Accessing the service mode to determine page count

To enter the service mode, perform the following steps:

Hold down the SELECT key and the CANCEL JOB key while turning on the printer.

Release the keys when all lights on the control panel are lit.

Press the right side of the MENU key.

Press the SELECT button. The message, Service mode, should appear on the printer display.

Press the MENU key until the message, Service menu, appears on the printer display.

Press the right side of the ITEM key until Pages = (the page count) appears on the printer display.

To exit the service mode, press the green GO button.

Measuring the resistance between fuser connectors J132-1 and J132-2

Measure the resistance between fuser connectors, and take the following steps:

If the range is not within 200kohms-500kohms, replace the fuser.

If there isn't any continuity between fuser connectors J143F (Neutral) and J142F (Hot) with the fuser removed is zero, replace the fuser.

If the range is within 200kohms-500kohms, continue isolating the issue.
