Cleaning Using The Cleaning Kit - Roland SJ-740 User Manual

4-2 Cleaning Using the Cleaning Kit

Cleaning using the cleaning kit should be carried out when automatic cleaning and forced cleaning from the [HEAD
CLEANING] menu fail to correct image drop-out. Remove any ink buildup of dust or grime around the printing heads,
which can cause image drop-out or ink drips. We also recommend performing periodic cleaning using the cleaning kit to
prevent problems like these during printing.
If image drop-out persists even after performing cleaning with the cleaning kit, or if the cleaning kit is used up, contact
your authorized Roland DG Corp. dealer or Roland DG Corp. service center.
The heads are consumable parts. The useful life is six billion shots per nozzle.
Before starting cleaning, read through this section carefully to familiarize yourself with the procedures, then carry out the
cleaning operations quickly and accurately.
Cleaning is performed while the caps on the printing heads are detached, so cleaning must be completed before the heads dry
out. It is suggested that cleaning be completed in thirty minutes or less.
If it appears that cleaning operations may take more than thirty minutes, stop the cleaning operations and follow the steps below.
1. Attach the cover and tighten the screws.
2. Press the [ENTER] key. (Cleaning of the printing heads starts.)
3. Again carry out cleaning using the cleaning kit.
