Question about Sharp AL 1631 Copier

1 Answer

What should I replace to stop repeated paper jams? The copies are made and the paper is passing through what I believe to be the corona, but the paper folds up like an accordion and the machine jams. Thanks for your help.

My paper keeps jamming


I can't believe no one has mentioned the fuser yet. Is the first page actually making it out all the way or is it stopping in the output?

Maintenance message kept appearing but could still use machine. With info from your site, I think I cleared it. However, we keep getting a message that there is a paper jam (Jam 50). Could find nothing...


Maintenance message is setted by the technician, the numbers of copies that you can make with the same drum is limitted by the technician, (100k) if you reach this limit the maintenance message appears, you have to replace the maintenance kit (the opc drum, transfert corona, main corona) to avoid the bad quality copy. if you need to work with the machine you have to call the technician he can increase the counter limit to clear the warning message.

We have a Sharp 1641CS copier will not feed or copy


Well one reason the Cartirdge is spilling is due to the cartridge backing up with toner everytime it tries to print, it misfeeds cause the paper feed tires need to be replaced,

The paper keeps jamming in my konica photocopier and the following message appears F28 3 Contact service department


F28 High voltage leak. (coronas)

The corona wires are arcing, it is located directly under the drum a unit with three thin wires. the end blocks go bad and it arcs causing jams and copy quality problems, replace the corona ***'y.

Other cause may be the High voltage unit for the coronas itself

Sharp AL1642 CS Copier Grinding noise and Paper Jams


Loud clacking sound, jamming in fuser ? sounds like the gear that turns the fuser are bad and not meshing together,
accordion jam is the fingers or claws that ride on the fuser roller are probably worn out ( these can be replaced usually 3-5 ).

You can buy the parts and replace them yourself if a handy person, not that difficult.

Canon IR105 and IR8500 Load paper Problem, Tray Suspend Problem, Paper Pickup and Jam Problem


WOW !!!! that is a list, but I will try to shed some light.

1-are the trays not being sensed in the paperdeck (optional paper tray capacity)
and the ones that work in the copier?/ a) the bord may be bad b) the connector may not have good contact
2-tray suspend

3-registration jam, a) the registration assembly is probably shorting out b) notenough sep causing the paper to rise up on the drum and then jam,

4-the paper sensor in the trays are in the pick up assembly tires, the ones that come down topick up the paper, there is a sensor that is loose but when it hits paper goes up, when no paper the metal plate goes up but has a hole for the sensor to fall trough and does not go up, giving paper empty.

5-I do not have any info on the specs for the corona wires, this is in the service manual

6-Sparking in the coronas is bad and can result in paper jams and holes in the drum, sometimes putting whiteout on the very ends of the coronas help, but it's better to replace, you can get the end blocks seperate.

7-Pre-corona assy' is to charge up the drum for fater copies, some techs do take them out, if all the wires are arcing then it may be your HVT (high voltage transformer) for the coronas going bad.

8-image is skewed only when using ADF if you put it on the glass it should be fine, the problem is the glass is too dry, try spraying some WD40 on the glass and wiping it off, leaving no residue just a slick smooth surface. the paper turns due to the dryness when fed on the glass.

9- Yes you are right there is no room for the paper to skew it would tear or get jammed if it did

hope I was of some help
