Cleaning the Printer
Cleaning the cabinet
The external cabinet materials and finish are durable and resistant to these items:
• Cleaning solutions
• Lubricants
• Fuels
• Cooking oils
• Ultraviolet light
The 7169 Multifunction Printer does not require a scheduled maintenance. Clean the
cabinet as needed to remove dust and finger prints. Use any household cleaner designed
for plastics, but test it first on a small unseen area. If the receipt bucket is dirty, wipe it
with a clean, damp cloth.
Cleaning the thermal print head
Caution: Do not spray or try to clean the thermal print head or the inside of the printer
with any kind of cleaner as this may damage the thermal print head and electronics.
If the thermal print head appears dirty, wipe it with cotton swabs and isopropyl alcohol.
If spotty or light printing problems persist after the thermal print head has been
cleaned, refer to Troubleshooting Problems on page64.
Cleaning the slip station
The slip station does not require a scheduled maintenance. If needed, clean the Dot
Matrix platen bar and roller with isopropyl alcohol to remove dust and ribbon ink.
Caution: Do not clean the carriage shaft of Dot Matrix print head. This may scratch the
shaft and cause high friction for carriage movement.
MICR Read Head
If problems related to reading of checks are encountered, clean the MICR read head by
wiping it with cotton swabs and isopropyl alcohol.
