Any way to print black-only document with defective color cartridge? (DJ500) I don't often have the need to use my DesignJet 500, so it wasn't a huge surprise today to find one of the ink cartridges reporting Out of ink (even though ink level is reported to be 64cc or 94%). The problem is that this issue prevents me from using the printer. Is there not a way to print my file using black only? I can't buy these cartridges locally and I need to print some construction drawings for a meeting tomorrow evening.
