Hi, It is most likely be
due to dust accumulation at the laser reflecting mirrors inside the copier, which partially blocks laser beams and results
in faint print. Therefore the
printer requires cleaning/ servicing by a professional.
You are using too much magnification. Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow if you have one. Practice focusing on a distant object during the day time..
check first if your printer can copy well. try to photocopy a document. and if it copies well, that means, its a problem on the part of the receiever, if it does not copy well, that means the scanner of your unit has a problem.
Make a copies with something with a lot of print. open top cover when the paper is 1/2 way through the machine. pull out the toner & drum unit's look at the drum is there a full image on the drum but not on the paper then it is a transfer problum. If no image on the drum then we have a laser unit problum. There is a shutter that opens when you put the drum in & closes the top cover. it may fallin out of place. hard to git at or somthing is blocking the laser beam ( paper, dust bunnyies or fourn objest ) hope this helps let me Know
If you know where the fly back is, ok open the casing and see at the
back of the fly back, there are two knobs, one for the focus and the other is
for the brightness. Try twist both and see which one is for the focus. Ok,
from the focus knob try adjustinguntil the fuzzy sight disappears. Try
this, I usually do it to screens with blurryappearances.
The traditional measure of image sharpness is stated in line pairs per millimeter ? abbreviated as lp/mm. In other words the ability of the human eye to discerned the number of high-contrast pairs of lines appearing in the space of a single millimeter.
It may help you to get a better result.
