Scheduled maintenance
In some segments of the printer market, the customer tends to print more than the maximum number of
prints that the throughput allows, exceeding by far the limit of the design. When this happens the customer
runs into print quality problems and continuous printer failures.
The purpose of scheduled preventive maintenance is to avoid these failures - ensuring a good performance
during all the product life.
Level of printer usage
Non-Volatile Memory (NVM) counters are assigned to counting the number of carriage cycles, carriage
distance, service station cycles, and ink in the waste management module. When certain components of the
printer exceed preset amounts of any of these counters, the front panel displays the following messages:
●
“Service Maintenance #1 required” (related to Carriage cycles and distance)
●
“Service Maintenance #2 required” (related to Service Station cycles)
●
“Service Maintenance #3 required” (related to Carriage distance and ink consumed)
When one of these messages is displayed, the appropriate service maintenance kit must be used to replace
the relevant parts of the printer. See “Removal & Installation” on page 271 when replacing the parts.
IMPORTANT: Both Service Maintenance Kit #1 and Service Maintenance Kit #2 contain, among the printer
parts replaced, all the parts contained in Service Maintenance Kit #3.
Therefore, when Service Maintenance #3 is required, you should check the status of Service Maintenance #1
and #2. If the status of #1 or #2 is close to 100% (for example, above 95%), it is best to perform that Service
Maintenance instead of #3, to avoid two interventions within a short period of time.
Service Maintenance Kit 1
Service Maintenance Kit #1 (part number B4H70-67103 for Latex 360 and 330 or B4H69-67046 for Latex
310) normally includes the following parts, although the list of parts may vary slightly:
●
Ink Supply Tubes & Trailing
●
Cable Carriage Assembly (with encoder sensor)
●
Cutter Assembly (Latex 360 only)
●
Belt Assembly and Tensioner
●
Encoder Strip
●
Scan Axis Motor
●
Carriage PCA Cover
●
SMK3
Clean bottom impinging surface with the provided brush.
Clean the printzone platen holes, and for the Latex 360; remove the platen, and clean the vacuum towers.
Execute all the “user” maintenance actions.
Reset the SMK1 life counter, see
3.1 Reset Maintenance Kit Usage on page 177. Perform all user maintenance
procedures after the replacement: clean and lubricate the slider rod and clean the encoder strip with water
and a lint-free cloth.
