CHAPTER 4
Maintenance and Cleaning
The e285 device has no user-maintainable parts. It can, however, be cleaned.
Surface
Cleaning
To clean the device, use a clean cloth slightly dampened with water and a drop or
two of mild soap. For stubborn stains, use alcohol or an alcohol-based cleaner.
Terminal
Contacts
Gently swab the contacts with alcohol or contact cleaner to remove the dirt. It is
important that the exposed contacts of the e285 battery stay clean and unbent.
Magnetic Card
Reader
Dirt accumulation can lead to MSR reading problems unless you clean the
magnetic stripe reader (MSR) on a regular basis (daily to once a week, depending
on usage).
Clean the MSR using commercially available card reader cleaning cards, or using
Verifone’s recommended MSR-cleaning card (PN 02746-02).
Smart Card
Reader
Do not attempt to clean the Smart Card Reader (SCR). Doing so may void any
warranty. For smart card reader service, contact your Verifone distributor or
service provider.
CAUTION
Never use thinner, trichloroethylene, or ketone-based solvents – they may cause
deterioration of plastic or rubber parts.
Do not spray cleaners or other solutions directly onto the keypad or device
display.
CAUTION
Avoid touching the contacts of the e285 battery. Finger oils tarnish contacts,
causing bad connections. When operating on battery power and experiencing a
high occurrence of bad or incomplete data transfers, clean the contacts
NOTE
If using a commercially available cleaning card, use ONLY an approved MSR
cleaning card made specifically for POS MSR terminals or Petroleum MSR card
readers.
CAUTION
If you find foreign objects in the SCR, send your terminal to a Verifone authorized
repair center.
Do not use Verifone’s recommended MSR-cleaning card (PN 02746-02) or
commercially available card reader cleaning cards with the SCR.
