HELP....I have unplugged the unit, cleaned the unit, wiped the metal connections with an eraser. I was told it might be the shutter not releasing. What can I do?

    try hitting it on the front side, sometime that will help, i did that to one here and that indicates that something is sticking. im not saying its a solution, just a quick fix. something is sticking perhaps it is the shutter. on the laser.

    swiftly hit it and see. as i said its not permanent solution, but a quick fix, you might have to take it in for repair since the shutter is sticking. if thats the case.

    i think its mostly the laser, the module is very cheaply made. Staple were giving these machine away to customers that buy alot of product from them. the laser are going bad, ive just checked one and no laser is coming from the machine.

O MY SOUL IT WORKED! I've tried everything before for months... unplugging, new cartridges, servicing, etc. I've always avoided jarring an electronic item, but hitting the front fixed it! A couple of open-palmed smacks above the paper drawer, and it printed this very page.

How discharge cleaning blade

Theres a lot of disassembly involved for that. You open the front door....unplug & remove the toner hopper open the right door & remove a metal cover...then take out the developer unit. Thedn back to the front to remove a cooling fan & then screws to take out the drum process unit to access the cleaning assembly and clkeaning blade. If you are not a copier technician....I would not attempt it and call one to get the job done correctly. I assume you must have streaks or lines on the copies which prompted your question.

Recently replaced drum cartridge on our Sharp AL-1217 photocopier and copies are now coming out smeared with toner. I have done what I can to clean the parts.

First of all, remove both toner cartridge and drum unit. Wipe the space they occupied with a clean cloth till you see its clean. Wipe also the upper part where the laser unit is, that is the place you will see a small glass-like strip above where the drum fits, till clean. Check that the paper tray is not dirty with toner and if it is , wipe it clean. Slowly turn the semi-circular feed rollers while wiping with damp clean cloth till clean. Then check that you replaced a new drum and blade and that the main charger above the drum is clean. Also check that the drum seal blade , that small nylon paper-like seal is not broken , and if broken reinforce with a clear cello-tape. Then, re-insert your cartridges back into the machine and a very clear copy will come out. Please try and you won't fail.

I have Panasonic Workio DP-2310 copier and there were multiple lines the length of the copy .I cleaned entire copy and drum area and installed new toner cartridge now the copies are coming out blank , no...

check you drum charge connection between drum unit and developer unit, two metal strips at back that contact when the two unit are closed. none or bad connection means no charge and then blank copies

Turn off the printer, and unplug the power cord. Remove the cartridges, then the printhead unit, clean the printhead in look warm water GENTLY. Dry completely, clean the contacts with an eraser GENTLY. wipe contacts with tissue, then re-install back into the printer, add the cartridges, so an alignment and a clean, then print.

The copies comes out totally black

H2 00 Thermistor open, your fusing unit needs to be serviced (cleaned or replaced)

The black copiers can be a number of things a few things to check and what the remedy could be;
  1. Open the right door, if you notice a lot of toner/developer spilt then you could be having a charge corona short (built onto the drum unit) clean corona
  2. Open the right door, if you drum (green or blue cylinder (depending on brand of drum) under your fuser) is coated with toner (should be all green/blue) then you could be having a drum short, replace drum unit for this.
  3. Open the right door and on the door towards the bottom is a metal unit with a white guide built on it (transfer corona) if there is a lot of toner/developer in it (looks dirty) then this needs to be cleaned or re-built.
  4. You also could be having a board issue causing the black copies.

This could also happen due to the censors.
Try these steps.

1. Take all the papers out from input tray.
2. Open the cart door & take the cart out,and let the door be open.
3. Turn Off the printer.
4. Clean the metal contacts on the cart.
5. Reinsert the papers & the cart.
6. Turn the printer on.

This could resolve the issue.
All the Best!!!!!!
