Step-by-step Procedure for Single Head Replacement
Review:
1. Single Head Replacement (SHR) is based on 4 major steps, as follows:
1.1
Identify the head to be replaced:
This should be done primarily by
performing a Pattern Test which will determine if any of the heads
needs to be replaced, according to the number and location of
missing nozzles on this head. Please note that missing nozzles spread
out over the head may draw a different conclusion, as opposed to all
missing nozzles being in one area. In addition, missing nozzles may
still be revived if head wiping is not adequate or wiper blade is
defective. Always perform purges, manual head cleaning and wiping
before determining final status of missing nozzles.
1.2
Preparing the printing block for head replacement:
This step is
done automatically by the Eden application during the Wizard
process. The application will empty the heads, and prompt the user
to replace required head.
1.3
Replace malfunctioning heads
: Remove malfunctioning head, tag it
and record relevant information with regards to this head [(1) Total
printing time (2) Head location in block (3) Head S.N. (4) Block S.N.
(5) known weight (6) malfunction description]. Insert new head.
1.4
Automated Calibration

‘Weight Test’. The user will be required to measure the weight of
printed cube for replaced head, and enter the result into the wizard
screen.
