Question about Office Equipment & Supplies
Turn on copier and after about 15 seconds it shows J50.
Copier also has a dark strip ,within which, letters double image (ie each letter repeats about 2mm from original). This dark strip is about three
quarters of the way down the page and and is about 70cm wide. This appeared right after I replaced the drum cleaning blade and before I cleaned the optics.
It neither had a dark patch nor was it double imaging before I replaced
the drum cleaning blade,before this, all it had was a striped line typical of a worn drum cleaning blade.
I then stopped the copier before the paper exited to check where the double imaging (and dark strip) was coming from. It was on the copy before it went through the heat rollers.
It was only after I had had the imaging unit in & out 3 or 4 times that
the J50 came up.
This is for a Mita 1560 Photocopier (analog)
J50 was caused by exit sensor not sitting correctly in its bracket,I fixed this by pushing it until it
clicked back in.
The dark lines & double imaging can be caused light getting onto the drum ,or if the drum gets
cold (so I have been advised) which one it was for sure I will never know because when I
returned the next day & fixed the exit sensor the copy was OK.
