Clogging gets worse after cleaning

InkjetMall Customer Support Printer Maintenance & Cartridges

Printed out a nozzle check and saw 2 small broken lines in my MK channel on my 4900.

I performed 1 or 2 cleaning and thought I would be good to go, but after cleaning clogging got worse and nozzle check now showed 4-5 broken lines.

why is this?

I eventually got a perfect nozzle check but wasn’t sure if this was normal.

thanks

It could be air in the lines or debris that is moved along the head, that finally gets cleared by the cleans.

I would do a small print after 1-2 cleanings; avoid constant cleanings.

Hi Stump~

Sorry for not responding quicker, I was involved in workshops and trainings all last week, and was away from my computer.

Did the missing nozzles occur either shortly after installing a new or refilled refillable cartridge, or after the printer had sat unused for a while?
As Ken suggested, it may have been caused by air or debris, and to avoid too many cleaning cycles.

Please let me know if this reoccurs, you have further questions, or there’s anything else I can help you with.
Best regards and happy printing~ Dana :slight_smile:
