When I make a copy of some documents with presses (marks from stamps) like ID, the copy doesnt contain any of those presses. So copy is a literally blank teplate of document without stamps! I guess its kind of problem with copier's exposure options and I wanted to correct its manually but whe I disassembled the device I did not found any variable resistors to correct the exposure settings. The problem is that copier doesnt copy semitone and light colours what on the copy supposed to be gray.
Is there any ideas what can I check and do? Does somebody know where is that goddarn variable resistors for exposure in canon pc-d320?
p.s. I guess it's not a problem of cartridge, scanner of printer parts. Cause it printing actually quite good.

Do you mean the Canon Pixma MX310 all-in-one inkjet printer? If you wish to print a copy without using a computer, first make sure that you have ink and paper loaded and that the all-in-one is on and the paper output tray is extended. Place your document face down on the glass or face up in the automatic document feeder. (Note: the scanner doesn't see the document if it is within 2 mm of some of the edges of the platen glass. If you use the ADF, remove any document currently on the glass.) Press Copy (if the unit isn't already set to copy). Check the default settings on the LCD screen and enter the number of copies desired. Press Settings to change any items and use the left/right arrows to change the number of copies, if needed. Press the Color or Black button to make the copy(ies). Color for color documents and Black for black & white documents. Press Cancel to stop copying.
If internally generated prints are good, but copied documents are bad then your scanner needs cleaning. This can be found in the document feeder section where the light scans across the paper. If both copied and internally generated prints are bad, then chance are, your toner/drum catridge has run out.
Has anyone changed the paper size in the paper tray to another size by accident? Have you tried the manual feed tray? If that copies the whole image then the problem is with the paper size input of the paper tray.
I had the same problem but it was caused by the scanner that was not running flash under the copier glass,if I remember correctly there are spacers on the scanner that keep the scanner to run exactly the same distance from the glass of both sides of the scanner.
On the other machine,I found a faulty scanner cable that cause a similar problem.
hi im jules_09,check the developer,if its past over 60,000 copies if
its over 60,000 copies you need to change the developer along with the
opc drum and cleaning blade or roller,all copiers need to be replaced
with new developer,opc drum and cleanign blade or roller when it reach
its copy life,that may be the cause of light copy of print
