A line could be anything from charge unit dirty, a rotational line on drum or possibly a fuser roller that has a line worn into it. Question? Are we talking a straight uniform black line or is it irregular fuzzy line that changes some? If it's fuzzy, probably charge corona wire or grid dirty or needs to be replaced.

Copy quality from my sharp AR 275 copier keeps fading away. I have replaced the drum. I cannot locate the corona wire. where is it located.


No corona wire is there on this model, you can find one saw teeth like portion inside the main charger it serves the purpose of corona wire you can find the charger assembly on the drum unit, you try to clean the charger assembly by washing it and drying it buy the sun light, better to replace the maincharger, drum, cleaning blade, and developer together.

Vertical Lines through incoming faxes and copies.


Sometimes you may see vertical streaks/black lines
on the faxes you receive. Either your FAX/MFC's
primary corona wire for printing may be dirty, or
the sending party's fax scanner may be dirty. Clean
your primary corona wire (see pages 13-18), or ask
the sender to make a copy to see if the problem is
with the sending machine.
Cleaning the Drum Unit
We recommend you place the drum unit on a drop cloth or large piece of
disposable paper to avoid spilling and scattering toner.
1 Carefully turn the drum unit upside down.
2 Clean the primary corona wire inside the drum unit by gently sliding the tab
from right to left several times.
3 Return the tab to the Home
position (  ) before
reinstalling the drum unit.

My ar275 copier has a problem with the developer unit. the developer leaks out when the machine is working. what is the remedy


The corona in the drum unit might be dirty which causes an arc that pulls the developer out, Take drum unit out and there are 2 black tabs with a screw in them, Remove the two screws and remove the corona and clean. Be very carefull not to scratch or touch the drum.

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.

Sharp ar-m237 copier


Direct light can effect the copies. Your unit may also need developer as well. If the developer is low or gone out of the unit, light copies will appear as well.
