Cannon cp 660 Flashes "clean density sensor" on menu when ready. I also get a half inch thick horizontal line across the center of the page on every print which is like a grey smudgy line. Any help on problem indication would be much appreciated. Thank you Dean

Does the printer have replaceable printing heads, or are they integral to the ink cartridge. If so they may need replacing or calibration. Another issue may be electronic contacts, check inside the printer and on the cartridges for any dirt or debris on the (usually copper colour) contacts on either end.

Also, if possible try the printer on an alternate computer to ensure it is not a problem with your software.

Kind regards, ACD

SOURCE: White lines in print

Hi, since you've already try some basic trouble shooting to your printer such as head cleaning & ink cartridge replacement. There's a big possibility that the nozzle on that printer might be mis-aligned or clog by dried inks & contaminants. The possible solution that we can provide to you (asside from head cleaning) is printhead alignment. If issue still present after doing that solution, your printer may require service.

How to use a stud finder

The stud finder works by picking up density of the product it is pressed and slid on..Turn your stud finder on make sure the ok light is on...then slightly press it against the wall or surface you are working with,,then slowly moved it right or left still against the surface. As the finder starts to detect more density "thickness" it will. Glow or beep depending what type you have..It will get brighter,louder or what ever it signals are while crossing the stud beneath the surface..keep moving until it stops then move back
again until it stops.....mark or note the position where the signal starts then find the middle...2x4's are 1 1/2 inches center should be 3/4 of an inch...good luck..

There will be a flap at the back that drops out and down to give access to the fuser for clearing jams and "straight through" printing. Four lines repeating down the page is equally likely to be be a mark on the cartridge drum, possibly from the Primary Charge Roller if the unit has been very hot or not used for a period of time in higher temperatures. Remove the toner cartridge and in LOW light manually rotate the drum using the gear at one end of the cylinder. Look for a scuff mark right across the drum or a black/grey line. You may be able to clean the drum with a cotton ball and alcohol. Try the print again and see if there is any improvement. If you have another cartridge in hand you might try that to verify cartridge or fuser.
