Problem is canon ir 400 close the front cover?

Hi,

if you've closed all covers and the error still exists, please restart the copier. If errors are still coming up, please check that all debris have be removed from your printer or any potential sensors . You can also clean the copier surface with material recommended by the manufacturer before restarting the device.

Thank you.

right cover sensor switch is not pushed well, pls check well

Either you misunderstand this message or the switch which says the door is closed is not doing so.

Front left or cover

Your connector is not good is connected to the DC control board. That connector is J112, which is located in top 3 of left to write.

it is related to FAN, check all the connection of fan.

E-100 is an error of the Laser Beam detect PCB. Either the laser unit is not working or the beam detect PCB is not detecting the beam. You can't see the beam so don't try. Since you are also getting a E-220 which is a Scan Lamp error. Most likely cause is a ribbon cable between the CCD unit and Image Processor PCB. You may need a tech to trouble shoot this problem

This not really a problem. Canon Copiers have various counters that track the counts of Various sized papers. Long, short and the like. The only counter that really matters in the 101 or total counter. This the counter that tracks every piece of paper that goes through the copier. This is the counter used to track copy usage. If you have a service contract this the counter the dealership will use to track copies for billing. Ignore anything but the total counter.

Try to open and closed the front door several times,If the left cover and the front door are closed properly and still showing "close front door" most
probably the internal contact of door switch are not good , door switch replacement is needed

Are you sure you have the right toner??? It says it is for the IR-200-210 or dose it say IR-330 & IR- 400? If you look on the inside front door cover there are pictures showing how to install the toner, also there are pictures on the box the toner came in and also the display sceen will walk you through on how to replace the toner.. It slips in only one way and push down on it till it locks in then pull the blue tab till it displays "STOP" then push it back in and the push on the black part on the front of the developer unit to release the toner bottle and close the copier back up and lok the blue lever to the left and you are done. Good Luck
