HP Deskjet F2140 All-in-One Printer - Manual (Page 97)

• Do not open the print cartridge door unless necessary. This exposes the print
cartridges to air, which reduces the life of the print cartridges.
NOTE: If you leave the print cartridge door open for a long period of time, the
HP All-in-One will recap the print cartridges to protect them from exposure to air.
• Clean the print cartridges when you notice a significant decrease in print quality.
TIP: You might notice a decrease in print quality if the print cartridges have not
been used for a long time.
• Do not clean the print cartridges unnecessarily. This wastes ink and shortens the life
of the cartridges.
• Handle print cartridges carefully. Dropping, jarring, or rough handling during
installation can cause temporary printing problems. If print quality is poor right after
cartridge installation, allow half an hour for the print cartridge to recover.
