The problem you discuss is relatively common for people who either use a
lot of coated paper (especially thicker weights) in their printer, or
after years of use.
A bit about paper misfeeds:
Misfeeds can manifest as the printer running paper through without
printing on it (this occurs when the paper arrives late due to slippage,
so it is rejected by the printer), or several attempts at feeding the
paper without success and then the driver and printer shutting down
(into pause mode), or when you find you have to help the printer to get
the paper to grab, or where the printer only will work for a few pages
until the paper begins to slip, or the paper tends to feed on an angle
and get damaged or jammed.
Most often, the problem is caused by glazing of the pickup paper feed
wheels. Some papers use coating such as kaolin clay, which is very
slippery, to create the special inkjet surface. As this surface rubs
onto the paper feeding and pick up wheels, the paper slips more and more
often, until it either caused the above mentioned symptoms, or the paper
feeds crookedly and may even get jammed in the printer.
To clean the rollers, take a piece of blotter paper or other
semi-absorbent uncoated stock (watercolor paper, for instance) which is
thin enough to go through the printer, but heavy enough to hold some
liquid and not fall apart, and lightly spray one side with either
isopropyl alcohol or ammoniated window cleaner. Avoid the very edge of
the paper, so it remains firm enough to allow for proper feeding. Send
it through the printer several times, flipping it each time so the wet
surface changes from top to bottom to top, etc., using the paper load
buttons on the front of the printer. This usually picks up and removes
residue from slick paper surfaces which may come off onto rollers, old
ink, etc. This also can help in cases where the take-up paper feed
wheels have become glazed with inkjet paper coatings, and the paper is
either not feeding at all or entering the printer on an angle.
After doing this procedure, be sure to run several pages of scrap bond
paper through the printer to remove excess cleaner and dry the rollers
fully prior to using the printer with higher quality paper.
If the paper feed rollers are very glazed, you may wish to use the
cleaning fluid mentioned previously on a foam rubber cosmetic swab, and
clean each pick up roller (there are usually two of them) within the
printer just inside of the paper feed area. These areas often have a
mylar plastic shield which may need to be moved to get to the wheel for
cleaning.
Again, after cleaning, run several pieces of scrap bond paper through to
dry all the roller well, so your better papers aren't ruined, or don't
transfer excessive coating back onto those rollers.
