After I clean the print heads, it will print a partial page, then it slowly quits again. I've tried the soft, medium, and hard clean cycles for the heads, no difference in performance noticed. Replaced the cartridge with a new hp. Started yesterday in middle of good-sized print run. Printer is a designjet 100+. Replace the print head, or?

Depending on the model of machine.
Either on the Menu on the printer find Ink Management or press the Ink Management button.
Print a Test Page
If no Magenta Dots showing then proceed to Cleaning and Clean the print-heads through the proceedures given on the machine.
Print another test page. If Magenta Dots are fine then cleaning done. if not then try cleaning again.
If still not fine then the machine will need to be cleaned professionally which will cost a reasonable amount. Most service fees are more that it is to replace the printer.
You have a blockage in the print head and/or feed line from the ink cartridge to the print head. One possible fix would be to make a pad of paper kitchen towel wet it and sit the print head on it overnight. With luck the pad will soak the blockage and draw ink through the head. Give the machine two self cleans and try a print quality test to see if you have made ANY improvement. If no improvement - forget it as the blockage has been there too long.
>Check ISS pumping, >Check ISS tubes is there air gap?>Check cartridge bag broken in side?>Check for leakage at cartridge bank & carriage assm.>Do the following force priming to fil ink in tubes as well as in print heads:****Hold the power button down and press the cancel button three times and the resume button three times.****Switch Off the printer and then On again in order to start the priming of the ink supply tubes.
Print head nozzles are clogged.This utility helps maintain proper operation of all nozzles in the printheads.
This is only recommended if you are experiencing problems with print quality such as banding.Three levels of recovery are available: soft, medium and hard. As a first step, the soft recovery should be used. If you still experience the same image problems, then select medium. Hard recovery should only be used as a last resort.
Perform the print head recovery For level 1 soft: Hold on button then press twice cancel button level 2 medium: Hold on button press teice cancel button then resume button once level 3 hard: Hold on button press twice cancel button then resume button twice. after completion of this process check the print quality, still not resolved replace print heads which print head not recovered.
The other week I had the black print head clog up, requiring daily nozzle deep cleaning [a normal 'ocassional' maintenance function]. Thought I needed a new Print head, so anything worth a try.
I loaded up an old black cartridge [I load all my own......always have] with Isopropyl Alcohol and ran deep clean on that cartridge a couple of times, then repeat printed [6 times] a page full of the number 8 in about half inch character size, to get the alcohol through the nozzles. then Deep cleaned again 3 times, to wash it through the print head.
I reloaded the normal ink filled cartridge and ran the '8' page again till I got good black output. It has now been working without problem, daily, for over a week. Clearly if it's a Magenta only problem, the cleaning as described above would be a bit different, as the magenta is one of 4 colour cartridges.
My printer does quite a lot of work, and was bought at least a couple of years ago, being used daily for alpha numeric and photo printing work. This was the first difficulty I experienced with it.
Hope the above might help.Ken
Did yellow and magenta print OK before the previous cartridges ran out? If so, it looks like your new cartridges are not working properly. Try another yellow and magenta cartridge - you can re-use the previous cartridges if they turn out not to be faulty. If new cartridges don't solve the problem, you can try soaking the print head, in case you have nozzles blocked with dried ink for some reason.
Turn the printer on, and as soon as the print head moves out of its parking position, pull the power cord out of the back, or turn the printer off at the mains. You may now carefully move the print head by hand over to the left hand side out of the way. Look inside the print head parking area on the right and you will see a small rubber cup that comes up to cover the print nozzles when the head is parked (to stop it drying out). Use a syringe or dropper to fill this cup with head cleaning fluid or distilled water. DO NOT USE TAP WATER. Carefully push the print head by hand fully into its parking position so that the cup full of fluid comes up over the print head. Do not turn the printer on at any stage in this process. Leave this for at least 24 hours, then turn the printer on and try a head clean/nozzle check again. If you get any magenta/yellow ink on the nozzle check, then there is hope! Repeat the head clean/nozzle check process 2 or 3 times, but not more. Leave for 24 hours for any air bubbles to disperse. If nothing, repeat the soak process once more. If still nothing, post a new comment detailing what you have done and the results.
Check your other colours. Anything other than a True Type Font is printed in colour shaded with black, so it sounds like you have a problem with yellow and cyan. Either the ink cartridges are out or the print heads have a blockage.
If the cartridges are not empty or v low, try sitting the print head over a folded paper kitchen towel damped with hot water for 10 minutes. Remove it and try your diagnostic again.
There may be a release lever for the print head assembly which would
allow you to remove the print head and clean the excess ink from it. If
it appears to get better the more pages you print it may be just a
matter of time and lots of pages before it cleans itself.
Try running the print head cleaning utility multiple times to help
reduce the amount of ink on the print head. This could take quite a few
times before it gets better.
