HP Designjet 9000s Series Printers Service Manual 5 Treat any media, paper, used cleaning and maintenance supplies, and wipes soaked with ink as combustible materials. Handle and dispose of properly. Do not clean the printer with benzene or paint thinner. This may damage the paint. Wipe the printer clean with a soft cloth. A cloth moistened with a neutral detergent may be used. Do not allow liquid to enter the printer. This may create risk of fire and electrical shock and cause a malfunction. Never touch the printhead nozzles. They can be easily damaged or clogged. Do not touch heater surfaces in the paper path. This may cause burns.
Take care when touching printer components near the heaters. HP Ink Cartridges must be installed before the “Install By” printed on the cartridge. Use of the Ink Cartridge 3 months beyond the “Install By” date may cause deterioration in print quality or a printer malfunction. Do not separate the cap from a new HP Waste Ink Bottle. The cap is needed to properly seal the HP Waste Ink Bottle for disposal. The level in the HP Waste Ink Bottle should be checked by visual inspection to prevent overflow. If the waste ink level is above the indication line, the bottle must be replaced with an empty HP Waste Ink Bottle.
The use of safety glasses and gloves is recommended when performing cleaning and maintenance operations.
