Now that you are familiar with the printing process, you can probably
guess some of the common problems and their causes even before I explain
them. The best way to determine the cause is to identify at what point in
the process the printer is breaking down.
Loose or smeared toner
Here’s an easy one. If the toner is loose (that is, not fused to the
paper), the fuser is not melting the toner, and thus the toner is not
fusing with the paper. Make sure the fuser is heating; if not, replace it.


Similarly, smeared toner happens because the nonstick coating on the
fusing roller is scratched or has baked-on debris. You can try to clean it
with a soft cloth and alcohol, but make sure you let it cool down first!










Note







In this
article, I recommend replacing certain parts, but unless you are
a technician working for an authorized service center for that
type of printer, you might not be able to get the needed parts
easily.






Smeared output can also result when you refeed a printed page into the
printer to make a double-sided page. This happens because the rubber
rollers that grip the paper to pull it into the printer can pick up toner
from the first side’s printing and smear it.


Vertical
white areas
To fix this problem, clean the corona wires. Why? This problem is
caused by either the main corona or the transfer corona being covered with
toner in a certain spot. A quick fix is to change the toner cartridge,
even if it isn’t empty. Because the primary corona is located in the
cartridge, this will correct problems with a dirty primary corona.

To clean corona wires, use a special felt-lined tool that comes with your
printer or use an alcohol-dipped cotton swab. But be very careful! Corona
wires are thin and easy to break with too much pressure. To locate the
primary corona, remove the toner cartridge and look for an exposed wire.
The transfer corona’s location depends on the printer, but it is usually
protected with a webbing of filament threads. Not all laser printers allow
you access to the transfer corona, so check your manual if you can’t
find it.
Gray mist
If the white areas look like they have been lightly sprayed with a
gray mist, making them look slightly dirty or dingy, the problem is also
likely to be a dirty corona wire. (See the preceding section.)

This can also be the result of turning the printer’s print density
control up too high. The newer the drum, the lower this setting can be. As
the drum ages, you must turn up the print density control higher to
achieve sharp black printouts. However, if you turn it up too high, the
entire page acquires a dirty gray tinge. Some printers include the drum in
the toner cartridge, so you get a new one each time you change toner. On
other printers, the drum is separate, and you must eventually replace it
when it wears out.
