The iTherm® 280 can be configured to operate with various power supplies. If a DC
power supply with less capability is used, the printer must be configured for reduced
power and the printer will print slower.

Operation Precautions:

Do not print without paper.

Clean the head with ethyl-alcohol after power is removed from the printer. This will
remove foreign particles or paper dust which may degrade print quality.

Be sure to set the paper width in the printer's configuration to agree with the paper
being used (58 or 80 mm width).

For DC powered printers, the cash drawer is supplied directly from the DC input supply. The
cash drawer requirements may affect the allowable range of voltages.
