My HP 9500 Scanner lately started to generate red images, even when sent to a folder, independant of the print engine which works perfectly. What can I check orhow can I resolve this?

Do you have enough disk space? Check if your C; drive has enough space. Normally C: is used as 'scratch area'. Try scanning intoa different location.

Did you resolve this issue?
If not check that the Scanner bulb is lighting. If not check the cable from the scanner to the formatter and seated correctly. The scanner or the formatter board may be bad.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Try go to system prefs, print and fax. Remove your printer from list then add it again. It may pay to uninstall software first, then reinstall

Routine maintenance and keeping full ink tanks will prevent this problem, however if you have the problem you can resolve it by doing the following:
1. Clean your print head using denatured alcohol solvent which can be purchased from most hardware stores. If unavailable, use 91% Alcohol (isopropyl alcohol (first aid antiseptic) which is available for less than a dollar at most Walmart pharmacy departments.

*Warning: You may want to use a pair of latex exam gloves as this is a messy process and can stain your fingers.
Time necessary 45-50 minutes
Supplies needed:
Isopropyl Alcohol or denatured alcohol
paper towels
latex gloves
sink, bowls and or basin
can of compressed air
very small screw driver
tablespoon or baby bulb type syringe
warm water

PROCEDURE:
1. Lift print head from printer. It pulls out easily because it is held in with the same down lever that holds the cartridge in place.
2. Put two layers of paper towels in the bottom of a dish to protect sensitive sprayer heads.
3.Put enough solvent in dish to cover the screens on which the cartridges sit when in use.
4. Take the two small screws out that hold the white ceramic piece
5. Gently, pry the ceramic piece back and away , to reveal the underside (No need to pull away the glued points on the sides.)
6. Gently, move head up and down to slosh solvent around it the best as you can. Use a table spoon or syringe to pour solvent over all orifices in the print head, turning it upside down and then back a few times.
7. Use canned air with a plastic straw to blow into and through all orifices, alternately sloshing/swishing and pouring solvent over head (be careful not to touch any of the holes, screens, or sprayer heads with anything)
8. Empty dirty solvent from bowl and replace with paper towels and clean solvent. Soak for approx 10 minutes. Rinse again with clean solvent poured directly on all parts, letting solvent overrun and fall into dish or basin.
9. Gently shake the solvent off the head, take it outside and spray with compressed air into all orifices to clear out and help evaporate any remaining solvent. Let sit on a clean paper towel for approx 20 minutes. (There may be a little ink bleeding out of the head, but once it dries completely it does not present any problems.
10. Reinstall head, cartridges and it will print like a new printer.

SUGGESTION: For many years of problem free printing, keep a double set of ink cartridges, one set full at all times. Whenever a cartridge runs out of ink, replace it IMMEDIATELY, with a new one or a refilled one. This gives the print head no chance to dry out and create clogged heads. Routine maintenance of cleaning the heads every 24 months does wonders for keeping your printer in new condition.

Hope this helps. .
