20 Most Recent HP Photosmart 7450 InkJet Printer Questions & Answers


It sounds like you have a fault with the black cartridge print-head. Converting a document to pdf makes it a graphic and all graphics are printed in colour shaded with black even if your machine is set for grey-scale.

If the black cartridge has built in print-head, take it out and try pressing the head to a tissue to see if it leaves a solid "footprint". If no footprint, dip the head into a saucer of hot water for a few seconds and re-test the footprint. If you get a solid line/bar of black the cartridge should be ok if not repeat the dunking but only for a few seconds at a time.
If the cartridge is just a tank that plugs onto the printhead you will need to try a couple of cleaning or "diagnostic" cycles. If still no go try placing a folded up damp paper kitchen towel under the printhead for 5 minutes. Unplug the machine power cable while the machine is busy to do this. Remove the paper pad and repower the machine. Try a test page to see if things have improved. Good luck.

Make "fast draft" your default setting, otherwise, whenever you open a new document, it will print it in "normal mode".

First things first... try connecting your printer to another pc or laptop and try printing... make sure spooling is on in the driver and there are no other programs running...

if issue reappears then

It sounds like your printer cartridges are the issue

I would try reinstalling them...

if that does not work then

I would try cleaning your printer cartridge...

Gather cleaning supplies:
Clean distilled water. Use bottled or filtered water if distilled water is not available.
Clean cotton swabs or any soft, lint-free material (coffee filters work well).
Remove both cartridges.
Unplug the printer.
Lightly moisten the lint-free cleaning material with clean water.
Clean the cartridge contacts. Avoid touching the nozzles. Replace the cleaning material if it gets dirty.

If that does not work then I would try ordering some new cartridges

When the majority of the references indicated as "obsolete model" is very difficult to bring the references to their local area. I suggest visiting these links:

1.- SAMREM35 (SAM REM 35) - AH5910006M REMOTE CONTROL SAMSUNG SCM7450
2.- SAMSUNG SCM7450 Remote Control (Original)

Hope helps. Your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Please describe more about your problem. If you've downloaded the drivers, have you installed them? That is, have you run the setup program for installing the HP7450 on the HP Pavilion computer? When you run the setup program, part of the process will search for the HP7450. Are you connecting with the USB cable and have you check that it is securely seated in both the computer and printer? Is your printer turned on so the computer can find it during the search process?

You should try a couple of ink cleaning cycles.

Frequently use of same refill cartridge some time becomes dead or print is not able to recognize you can try with installing new one. Just follow these steps if it works but I advised you to change the faulty cartridge

Check to see if the installed cartridge is the correct one for the printer. If the cartridge is the proper part number, remove the ink cartridge and make sure all the packaging tape has been removed from the copper circuitry strip on the backside of the cartridge. Reinsert the cartridge and try printing again.

If the error continues, remove the cartridge again and clean the copper circuitry strip on the backside of the cartridge, and the contacts inside the printer, by following the instructions below:

1. Use a clean, dry, soft, lint-free cloth. Locate the copper-colored circuitry strip on the back of the cartridge.

2. Wipe the copper-colored strip with the dry cloth. Use an upward motion, from the nozzle end to the top of the cartridge. Do not wipe the nozzle end of the cartridge or touch the nozzle plate. Wipe the contacts only once.

3. To clean the printer contacts, carefully look for fibers or contamination on the electrical contacts inside the carriage assembly, but do not wipe the printer contacts with any object. The contacts in the printer can be damaged if too much pressure is applied during a wiping process. Try to remove any visible attached debris within the carriage assembly by gently pulling the debris off with your fingers. If the carriage contacts show noticeable damage, contact the Customer Care Center listed in the printer's User's Guide.

Reinsert the cartridge and try printing again. If the error continues, the cartridge may need to be replaced.
Hope this helps. Please rate my response.
Thanks.
Have a good day
