Problem: Just installed a new cartridge and machine still says "Toner
Diagnosis: Remove the cartridge, gently rock left to right,
reinstall. Toner may have compacted during shipment.
Problem: My newly installed cartridge won't print at all.
Is tab pulled?
|Printer Problem: I am
getting blank, or very light, areas on my printed pages.|
Cartridge may be out of toner. Insert another one to check.
|Printer Problem: Multiple lines
on edge of paper or thin consistent lines anywhere else.|
Drum in cartridge possibly defective. Switch cartridges to test.
|Printer Problem: Three equally spaced (from each other)
black spots on every printed page. |
Diagnosis: The drum is damaged.
It will need to be replaced.
|Printer Problem: Multiple random
spots (not specks) on every printed page. |
Diagnosis: Catcher blade
in cartridge has been damaged.
|Printer Problem: Toner is "smeared"
all over the printed page. |
Diagnosis: For whatever reason, the cartridge
wiper blade is not doing its job. Replace cartridge.
|Printer Problem: There is a white
line, up and down the page, where the cartridge is not printing. |
A piece of abrasive trash may have been pulled up into the cartridge. Take the
cartridge out and turn it upside (keep it away from sunlight). Push the spring
loaded piece over the drum, back, and look at the drum. If it looks like a white
line running all the way around the drum, it is scratched and will have to be
|Printer Problem: All of a sudden
there is a big blank space, on the page, that isn't printing. |
Follow the same procedure as above. Also look at the drum through the small slit
at the top of the drum. You are looking for a small piece of paper trash or even
an adhesive label. Remove it. Be careful to not scratch the drum.
|Printer Problem: A thin white space, running left to right
across the page that hasn't printed. |
Diagnosis: The drum has probably
been damaged by light in that area. It will need replacement.
|Printer Problem: When opening the bag on a new cartridge
you notice toner all over the cartridge and maybe even loose in the bag. |
Diagnosis: Stop! DO NOT put the cartridge in your printer. Put it back
in the bag and call your supplier for a replacement. Something is not seated correctly
in the cartridge and is allowing toner to fall out. It may have happened during
shipping, but regardless of why, it won't self correct and will just make a big
mess inside your printer.
In Conclusion: Some problems not listed
won't even occur if you will remember that your laser printer is an electronic
piece of equipment that needs to be protected and maintained and is not indestructible.
Many folks never think about protecting their laser printer from heat, dust and
humidity, or of even occasionally gently cleaning the inside (without taking it
apart). In this case, an ounce of attentiveness is worth a pound of headaches.
Some printer specific problems With over 500 different laser printer types
still in use, it is impossible for us to even begin to list all the possible problems
and solutions. Our short list is just for a hopefully quick answer.
EP-4/5 (EX) Cartridge
|Printer Problem: Spots and smudges of toner dropping
down the center of the page |
Diagnosis: Defective toner bin. Change
cartridge as it will get worse.
|Printer Problem: Double imaging
(a ghost print appears) or page is "trashy" with specks. |
Two possibilities. The moisture content of the paper could be too high. Store
paper in a temperature controlled area. The transfer roller could be going bad.
This is the spongy feeling roller in your printer, that will be right under the
cartridge head when you put it in your printer. You can replace the roller yourself,
for under $20.00. Note - You can have this problem when trying to print sublimation
transfers, but sometimes not see it (yet), when using a regular toner cartridge.
Sublimation toner is coarser and goes on the drum much heavier than regular toner.
|Printer Problem: Lines down the
page, lines kind of wavy and/or "trashy" looking page. |
The corona wire in the cartridge may need cleaning, although the one in the printer
is usually at fault. Your owner's manual will explain the proper procedure. Short
version- The corona wire can be reached through the top front slot of the cartridge.
Use a Q-Tip and the touch of a butterfly. Note - Because there are still so many
of these old (but reliable) printers still around, it is worth noting that the
HP-II & III and HP-IID & IIID all use the EP-S (EX) cartridge.
|Printer Problem: Solid black paper
or multiple black lines, horizontally across the page. |
PCR (charge roller) is loose or defective in cartridge.
|Printer Problem: Double imaging
(a ghost print appears). |
Diagnosis: Three possibilities - PCR is defective.
Transfer roller needs replacing. The fuser needs replacing.
