Re: it makes a clicking noise
What I have seen cause that is the drive belt to that transport jump. The second thing I have seen ,and more commonly, if the clicking noise is not that bad and not causing jams is this. The opening in the drive gears is a "D" shape. It is rounded half way then straight in a "D" shape. What happens over time is the corners of the d shape round out a little and you get a clicking noise because of the shaft hitting the the flat spot, because is has some movement due to the wear. You can generally just put some grease into the D slot and that will cushion the movement and stop the clicking. Or just leave it alone if it doesn't bother you. Jamming will more indicate a jumping belt, not jamming will more generally mean some wear in a D slot.

could be a few things... take out the drum and make sure the toner is put back in. then keep the right side door open and push the silver metal flap down near the back of the door opening (its the interlock that tells the machine the right side door is closed) and see if the noise occurs. if it does then you no its not the drum. so u can reinstall it. try to pin point the source of the sound with the right side door open. could be one of the many gears in back or the fuser (which is above the green colored drum) 4 screws and one wire harness takes off the fuser and u can physically inspect to see if the gears are missing any teeth or the bushings are broken. if all looks well then reinstall turn machine around and take off the back cover (6 screws) wiggle it off and turn the machine on and look closely at all the gears on the left(looking at the back) top side. when it starts it warm up process check to see if any gears are making the sound or cracked. if those gears are shot u mught need a new main drive assembly which is really difficult and time consuming to repair.
If you mean its flashing "E3-40" ..then it thinks there is a problem with the copy density sensor.
This sensor is located near the drum inside the machine.May just be dirty.
Doubt if this is something the average user can fix.
this printer uses leds to charge drums. if you lift top cover you will see 4 black windows ( 1 above each drum) make sure they do not have toner on them. green usually means you have some toner on the magenta led which causes missing magenta (yellow and blue make green) if it is on black and white prints it could be something else like a pile of toner under transfer belt (which you can pull out, after you take out drums) check the leds first
Well, if the light under the glass doesn't come on, that means that black copies can hapen. Nothing to do with the drum or drum unit. Either the lamp burnt or the protecting fuse is blown. If you take out the glass, you can mouve the carriage with the mirrors to the right and you can see the exposure lamp. If it has dark ( like silver) bands on it, the lamp is burnt and its brightness will not be enough to make a copy. CHANGE THE LAMP. If the lamp is ok check the thermic fuse wich is in touch with the lamp carriage, and normaly it burns when taking a lot of copies in one go. The drum is a red cilinder that is in drum unit next to the developer unit where you put the toner. If you open the ma chine you can see it about the midle just above the transfer corona. If you don't get it right i can explain how to change the drum. GOOD LUCK.
that really sounds like a defective toner cartridge. Either there was no developer in the cartridge or the metering blade that limits the ammount that gets onto the roller is bad.
Has to be the toner cartridge. Unfortunatly that may have also ruined the drum and cleaner within the drum cartridge. Return them for an exchange.
The reason it is running and running is that it is trying to read a patch that is developed on the drum and add toner to make a dark enough copy. And that definatly is not happening.
If the laser was not turning on, the machine would come up with a L something code. Besides if the laser was not comming on, the paged would be blank.
You can pretty much eliminate everything but the toner cartridge.
My machine had the same problem. A service tech looked at my machine and pulled out the OPC Belt Drum Unit. The drum unit had a few issues: 1) jagged rips in it, something caused by running papers through that had staples or paperclips in them. So when the drum turns, it scrapes other parts and the machine sounds like its going to drop all its nuts and bolts--at least mine did!)! and 2) the spindles from the OPC unit has come loosened and fell off. The spindles and plastic cogs were found way at the bottom of the OPC Drum slot. This too was thought to have added to the rips in the drum.
I replaced the drum ($399 was the cheapest I could find) and the problem went away.
-Open the Front Cover.
-Remove the Toner Cartridge
-Remove the Drum Cartridge
-Next locate the black gear attached to the end of the Drum and turn it with your fingers.
-Check to see if the gear is locked, or difficult to turn. The gear will only turn in one direction.
-If the gear won't turn at all, or if it catches while you are turning it, or if you hear the same noise when you turn the gear that you heard when the machine was on, the Drum Cartridge is the cause and will need to be replaced.
If you open the cover and remove the toner/drum unit, you will see (on the left side as you remove) a small hole with two triangle teeth. on either side of this hole are two small phillips head screws. this is the problem we had with our clicking noise. As the machine tries to turn the toner/drum, the innards of the toner are becoming harder to turn. So the part of the fax machine that fits in the hole end up stripping the teeth in that hole. If you have an old toner cartridge, you can remove the gearing from it (where the small phillips head screws are) and use it to replace the gearing on the newer cartridge. Or go buy a new toner cartridge.
