Replacing the Printhead
The KR403 printer has a new adjustment free printhead. You only need a #1 Phillips
screwdriver. No alignment or printing special test patterns.
1. Remove the two screws securing the printhead and its ground wire to the printhead
assembly.
Caution • Prepare your work area by protecting against static discharge. Your work area
must be static-safe and include a properly grounded conductive cushioned mat to hold the
printer and a conductive wrist strap for yourself.
Caution • The printhead becomes hot while printing. To protect from damaging the
printhead and risk of personal injury, avoid touching the printhead. Use only the cleaning
pen to perform maintenance.
Caution • Always disable printer power by un-plugging the printer from the kiosk power
supply or turning off the printer and/or kiosk power.
