Today the display indicated that cyan ink was low, so I inserted an ink block in that chute. When I closed the lid it still did not feed down the chute. However, the printer recognized that there was a problem and the display prompted me to open the ink loader door and then close it again. Several rounds of this (prompt on the display, open, close) had no effect. I grabbed the ink block and shook it back and forth in the slot, then closed the door, and it finally did feed down the chute. It appears to me to have been a mechanical problem.
Ever since I received this printer (I got it as a replace ment for a Phaser that was under a service contract and couldn't be repaired) I have be disappointed in the quality of the mechanical parts. The ink feeds into the chutes inconsistently (sometimes they stick at the top, sometimes they feed down immediately). It makes lots of loud noises, clunks and clicks, and is simply not as well built as the Phasers I've used for years.
