Designjet 500 ISS error

HP Recommended

I have a Designjet 500 ISS that has the identical error with 2 cartridges being faulty display AFTER I replace the ISS with another one.

 

What else could cause this error?

Bad ink tube assembly?

No error codes on power up.

 

Previous ISS was used. Worked fine for 18 months. Then flashed solid rectangle on display and '!' for 2 cartridges.

Replaced with another used ISS. Same display errors on 2 cartridges.

Maybe I am missing something here but I do not see where you tried any new cartridges. Maybe the two cartridges just went bad or as I have seen one bad cartridge causes another to show as bad even if it is not.

I've had this happen twice. The first time, one of my OEM ink cartridges had a bad chip, giving me the "!" on 3 of them. I solved that one by process of elimination. As an aside, the bad chip was on a cartridge that was nearly full. Not wanting to waste the ink, I pulled the bottom cover (along with the chip) off of an empty cartridge and installed in on the faulty cartridge. Yes, it warned me that the cartridge was empty for a long time, though it wasn't . I cut the top off of the cartridge for a visual indication when it got low. The little bag in there will shrink a lot as the cartridge empties.

 

The second time, I tried a set of non-OEM refill cartridges that have the automatic reset chip. These are fickle and will throw random "!"s at you, sometimes in the middle of a print job. Lesson learned.

 

Now, I only use genuine HP ink, but I only buy it on Ebay and only if it is expired AND factory sealed. I'm talking $5.00 to $10.00 for a $70.00 cartridge! The notoriously unreliable refills cost twice as much.

 

That expiration date is BS, the cartridges work fine even 10 years past the expiration date. I think the date was just a ploy to sell more ink, because it does not go bad. In the end, it works out great for me, because the price goes down and soon as that expiry date comes and goes. I have large photos on my wall that I printed years ago with 10 year old ink, and they still look perfect. The secret is to always use genuine HP paper and ink, but feel free to ignore the expiration date. I only buy factory sealed paper, too, the age of it doesn't matter.
