Anyone see this before? Excess ink (and what looks like optimizer) on the maintenance cartridge fiber roll material. (see pics below). This is happening on our HP Latex 630. Has happened twice now (both times on separate maintenance cartridges).
Not sure when this ink buildup occurs (our guess is during "standby mode" automatic maintenance functions overnight). Whenever this buildup occurs, printheads (particularly the LM/LC printhead) seem to start banding severely. Upon examining the printhead nozzles, there's always a dried layer of ink covering nozzles (clearly the dried ink is coming from the maintenance cartridge ink buildup on the fiber material). This printhead nozzle clogging issue happens over and over after cleaning the printhead manually by hand until we pull out the maintenance cartridge and manually pre-feed the fiber material roll forward in order to get the excess ink areas out of sight of the printheads (by using the plastic wheel on the bottom of the maintenance cartridge and spinning it by hand). Is this normal?
