There's really not enough info we can provide to explain the true cause of a sudden failure that prints blank pages.

That said, a possibility is failure of the purge unit under the parking pad (particularly if this suddenly happened immediately after changing carts). Typically this will occur with black pigment ink or all colors, but not both colors and black pigment simultaneously...

The reason Auto print head alignment fails is that auto alignment requires a pattern be printed to enable the printer to read the misalignment, If nothing prints, misalignment cannot be measured.

Thanks for reply , how to fix this

You can test the purge system for proper operation, and if it is clogged (very unlikely for both color and pigment to clog simultaneously) you might be able to clear it.

1. After performing a single deep cleaning cycle, remove and blot the printhead nozzles ONCE, against white tissue carefully and see if there is a black line and colored lines transferred from the PGBK nozzles to the tissue. If none, there's no ink at the nozzles.

2. Reinstall print head and inks and power down the printer by pulling the plug (don't use the on-off button). Locate the two "parking pads" wherethe printhead rests while off, probably on the right side, and apply a Milliliter or two of Original Windex (contains ammonia-D) to the parking pad with a syringe or eyedropper. The intent is to build up a standing puddle of Windex atop the pad that will stay there for a minute without draining away. Use more Windex as required but don't exceed 5 ML. If the standing puddle cannot be built and stay for a minute, this is evidence of a leak in the purge system (small hoses becoming disconnected somewhere is most likely). With this leak, the vacuum pump (a small peristaltic pump) will not pull a vacuum on the print head during cleaning.

3. IF the puddle on the parking pad remains for a minute, plug in the printer, close the cover, do a regular clean cycle. Re-open the cover and examine purge pads. Both should appear completely drained of the puddle, revealing the texture of the ceramic insert that fills the space within the rubber rectangular gasket. If there is still evidence of a puddle, then this is indicative of a clogged purge system. If the purge system is clogged, then, again, the small vacuum pump will not pull a vacuum on te print head during cleaning.

Please advise us of the results of the three tests above. Don't bother with #3 if you can't pass #2.

Thanks for reply but i realy have no idea what purge system is, beside i put print head inside windex(with ammonia) for about 4-5 hours , when i put or softly rub my white tissue paper both color and pigment ink leak, but still print is blank

The purge system is a means of pulling a slight vacuum on the print head nozzles ,while it is "parked" on the right side of the printer. Since you appear to have ink in the nozzles via a (questionable) tissue test, you may have a logic board of print had issue. Sorry, but your printer may have failed.

Hellow now i replace new print head still print is blank ? what to do ?

IMO, you have done all you can. Try another printer.
