Re: Infoprint 40 with 454 Fuser error
Sure.. the 654 is an MCU communication error, so the MCU card is probably bad (it's located near the front left side of the printer, under the operator panel). If the MCU is good, the controller card is the 2nd most likely suspect.
The least expensive way to fix the problem would be to purchase a used Infoprint 21 with a bad fuser (one that is posting a 454 error), and put your good fuser in that IP 21. Then make sure that the controller card in your IP 21 is good by swapping it in the operational printer, and sell the good controller card -- you might come out a few dollars ahead in the end.

1 +24VDC CHECK Measure the voltage at P/J456-1 and FG on the I/O PWB. Is there +24VDC between J456-1 and FG? Yes: Replace the “Fuser Fan” No: Use the Block Diagrams in the printer service manual to troubleshoot a loss of +24VDC
2 The following printer FRUs and areas are associated with this specific problem. One or more of these FRUs or areas may have failed partially or completely. If you cannot isolate this problem using the steps in this Service Check, replace each FRU or troubleshoot each area listed below, one at a time, until you isolate and solve the problem. • Wiring and connectors linking the FRUs • I/O PWB
There is a heater control problem in the fuser. The fuser is the assembly of heated rollers in the rear of the device. The most likely cause is either a blown heater element, or perhaps a faulty temperature sensor. Usually we fit an exchange fuser assemblt to fix this.
A 925 Fuser Error indicates that the wrong fuser lamp or the incorrect fuser assembly is installed.
If this error appears shortly after the fuser unit in the printer is replaced, put the old fuser unit back in. If the error message goes away with the old fuser unit, please check that the new fuser unit is the correct one for this printer model.
If the printer has not recently had its fuser replaced, plug the printer directly into a wall outlet. Surge protectors and power strips can sometimes regulate the voltage to a fault for the printer. If the printer is already on a wall outlet, plugging the printer into a different outlet may solve the problem. Keep in mind that there is no need to have the printer connected to a computer during testing for a fuser error as any pages to test the functionality of the printer can be processed internally.
If you have tried the printer on other wall outlets and the 925 Fuser Error still appears, the printer will require service to clear the message.
920 .06 Fuser is not increasing
in temperature even
though the lamp has
been on for an extended
time. Fuser page count
between 0 and 99,999.
• Fuser is not receiving AC power.
• Poor supply line voltage.
922 fuser errors is a bad fuser - you might try turning off printer - holding the select and return button down at the same time - turn on printer - HOLD buttons until it starts inting (about 15 sec) and the arrow over to print test pages - if the error doesn't return - repeat a few times.... this may by pass the error.. then power off - ON and see if problem is gone. replace fuser if not
Check the FUSER, I think your exit sensor is bad.
If you open the rear door, look inside where the paper starts to come out of the printer, you should see a small lever that triggers the PAPER EXIT sensor. It might be hard to see. If it is not broken, you need a new FUSER.
