Printer error my printershowing error and reset power supply

The code of PO2 is 5100, which means that the pen holder of printer cartridge cannot be reset normally. The most common problem occurs in the refit machine. If the supply pipe is too tight, this error will be reported, and the problem will be solved as long as the pipe is loosened inside.
If there is still an error after removing the connection, it should be that the coding tape behind the pen holder is dirty, the position of the pen holder is identified with a problem, and there is a failure of the cleaning unit, which can't move the pen holder

Title : E001 Error Code That is Not Resetable Error : paper jam
When the machine powers up the E001 error code is displayed but cannot be reset. (Note: The reset procedure for an E001 code is COPIER>FUNCTION>CLEAR>ERR)
Workaround :
In this case, the Main Power Supply PCB Assembly was replaced. The machine was powered up and the E001 code was able to be reset. The part number for the Main Power Supply Assembly is FM2-0260-000.
Remember, if the fixing unit circuitry has an open or a short, the code may not reset. Be sure to confirm the fixing unit wiring and try resetting the code before replacing the Main Power Supply Assembly. Canon USA, Inc. Systems & Technical Support Division1-800-528-2830

The Samsung printer error code u1-2320 is related to fuser that means the fuser unit fails. Need not to worry; this error can be encountered by many Samsung printer users. ... The Samsung printer error code u1-2320 is also the fuser error; this might be resolved just simply power off the printer.3

In most cases the printer driver software can have errors while being in use or is shut down. So to reset remove your printer from the PC and uninstall the printer software. Now reinstall the printer software and then connect the Printer to be detected as a new hardware as it will be installed. Now check the printer properties to see the ink levels.
Activate head cleaning before a test is taken . Sometimes it is possible that the main SMPS power supply has failed or has a defective output voltage . So please remove the power supply and check for bursted tank capacitors that can reduce the DC output.

if you are using any surge proctector to connect the printer to power source remove and connect directly.reinsert the catridges properly and unplug the printer from all source of power supply.wait for some minutes then power back,try it twice again if the problem persists unplug the power cable from the printer when the printer is powered on

• wait for some seconds then power back

it may be the power supply itself! have any of you tried using a different power cord? the problem may not be in the printer but in the cord itself. i have 2 hp 6310's that were giving me the 'reset power' error. when i changed the POWER CORD, that error message went away and it went into the insert cartridges mode. good luck.
