I've had my HP 7740 printer for about 4 months from new and now it's refusing to print due to a "supply system problem". Upon trying to get the printer running again and having varying ink low messages, all cartridges have now been replaced. However, the printer thinks the cartridges are low as below and there's an error with the yellow.
Checking inside the printer and was surprised to see alot of ink splashed on various parts. Is this normal and why the print levels have now dropped?
Any help would be appreciated as its a new printer that I currently can't use.
On the right side of the carriage, when the printhead docks to the right, there you should expect to see ink spills as this is the waste area where the carriage is expected to spill remaining ink.
Please show the exact error message, which should likely indicate an empty ink cartridge, as you cannot print with your printer with any missing ink, and from the screenshot the Yellow ink cartridge is empty.
You cannot print with the printer with any missing ink cartridge, as listed by below document:
I can also see that the other cartridges are quite low so be aware that upon replacing a cartridge the printer preparation consume some ink, so you would likely need to have the other ink cartridges available for replacement soon:
