Question about Xerox WorkCentre XD103F All-In-One Laser Printer

1 Answer

Hi, out of normal operation, I got an error code "H4" or "4H" (displays "H" and "4" alternately) which I cannot remove. The printer starts up immediately showing this code, then shows no reaction to anything. What does this code mean? Is there a hidden reset switch? Thx, Kanima

H4 means low fuser temperature.

Try first resetting the code.
When display goes blank enter 14 using the copy count numbers and press START button. Wait for the copier to restart does not turn off by itself , turn it Off and back on manually. If the H code comes back, then you may need to replace fuser unit. Fuser power supply must also be tested.
If the reset does not work contact Xerox at the number listed on manual.

Dryer will not start display works, when i push the start button it just beeps and does nothing, shows a E01 code.

Hi, this is what the error code means,

E1 or E2 Thermistor Failure The dryer will not operate if the exhaust temperature drops below 18 degrees F. or exceeds 250 degrees F.

When the thermistor circuit is open (>50K ohms), the error code E1 flashes in the display.

When the thermistor circuit is shorted (<500 ohms), the error code E2 flashes in the display.

Normal thermistor resistance values:
60 degrees F. - 15.3K ohms.
70 degrees F. - 11.9K ohms.
80 degrees F. - 9.2K ohms.
Hope it helps.

One number of photo copy machine drum cartridge wasinstalled. It worked once. Now machine is showing letter H and 4 flickering alternatively on the screen. Because of this none of the function of machine...

This code is almost always a false code. I would try clearing it by entering the following key sequence:
Press "Clear" then "Exposure Mode" then "Clear" then "Exposure Mode" (Note that the exposure mode key is the far left key and that these 4 keys must be pressed within 4 seconds)
The display should have gone blank if these 4 keys were pressed properly.
Now enter 14 as if you were making 14 copies then press the Print Button.
This should clear the H4 code and the machine should operate normally.
If not and the H4 comes back then you have either a thermal fuse or heater lamp failure.
Good Luck

THS Error on warrantee printer tally serial printer

The print head operating temperature may need to be calibrated for the operating environment of the printer.
The print head cable may be damaged or incorrectly plugged into the print head or logic board.
The print head may have a fault.
There may be a fault on the logic board or interconnect board

The first thing that I would recommend doing would be to calibrate the print head operating temperature, this can be done in the following way;

·Start with the printer powered OFF and at normal room temperature
·Hold down the ONLINE and SETUP button and power the printer back on
·Keep the ONLINE and SETUP button held down until the display reads ‘PRINT TEMP. CAL’ along the top line
·Press the button under ‘TEMP CAL’ (button 3)
·Using buttons 2 or 3 change the Temp Setting to match the temperature of the room the printer is used in (change this value by at least 1 degree even if it is correct to force the printer into recalibrating.
·Then press SET to save the settings.

Once the Temperature has been recalibrated power the printer OFF and back on again, this should resolve the problem.

If once the print head temperature has been calibrated the printer displays ‘Head Hot’ or alternatively displays a ‘THS’ error this indicates the printer has a hardware fault. The next step would be to identify which part may be causing the problem.
I would recommend first checking the carriage cable to ensure this is not damaged and makes good contact at each end. Then you would need to look at a logic board or print head failure.

Canon Pixma MP150 Error code E 42

Had exact same problem. Scanner light should come on at power up. Found ribbon cable connecting scanner unit to base had come unplugged from socket on circuit board. The ribbon cable is one of three found near back hinge of scanner and is hidden underneath the other two. It should drape over the edge of circuit board and then plug into small recepticle on inner side of board. I plugged it in and printer works again. Hope this helps.
