Removing the Receipt Cover
1. Turn off the host system or unplug the power supply (if used).
2. Disconnect the communication and power cables.
Models receiving power from the host system (integrated) use one cable for
communication and power. Models receiving power from a power supply (remote)
use one cable for communication and a separate cable for power.
3. With the printer facing you, lift the receipt cover, pull it upward and slightly to the
right to detach it from the printer at its hinges.
While removing the cover, hold down on the printer with your other hand.
Removing the Platen (Non-Knife Units Only)
The platen can be replaced on non-knife units only. In some cases, it may be better to
replace the entire receipt cover.
Caution: Be careful when removing the paper guide. It may break. If it does break, you
need to replace the entire receipt cover. The paper guide is not stocked as a separate item.
1. Remove the paper guide by pulling out from the center.
The sides should bow slightly releasing the paper guide arms from the tabs.
2. Remove the platen by prying on one side of the platen shaft with a screwdriver from
behind until it pops out.
The other side will slide easily out.
