"Duty cycle " is the percentage of time that the specied "Amount of solid coverage" can be printed

during a one minute period of time. Example: at 20% solid coverage and 35°C (95°F) temperature, a 50%

duty cycle is to be used, resulting in 30 seconds of printing and 30 seconds without printing.

Avoiding harsh environments

The printer is a durable piece of equipment and can withstand a range of physical environments. However, the

printer’s internal mechanical components are vulnerable to dust and airborne chemicals, particularly in places

like home improvement stores, garden shops, and warehouses. In these kinds of environments you will need

to make sure that your printer is cleaned regularly so that it keeps working properly. HP recommends regular

periodic inspection and general cleaning of the MICR read head, sensors, carriage shaft, and both printer

mechanisms.

Paper

IMPORTANT: Use of paper that is not approved for the printer can damage the printer and void all

warranties. See Paper requirements on page 27 for more information.

MICR heads

IMPORTANT: Make sure you don’t insert a check into a printer with a paperclip or staple attached.
