DESCRIPTION OF THE MONTHLY MAINTENANCE SCHEDULE
28.10 Technical Reference Manual Chapter Issue 5, Aug 14
DESCRIPTION OF THE MONTHLY MAINTENANCE SCHEDULE
Introduction Two modules form the basis of the monthly schedule. The process requires that
each month a machine repeatability check is performed on Squeegee Pressure
and the X, Y and Theta axes. This is done using the Statistical Process Control
(SPC) data collection program (where available).
Module 1 The first module comprises the following elements:
• SPC Alignment Check - used to set a benchmark each month, the hard-
ware is checked to give a snapshot of the machine condition, performance
is monitored to predict failure before it has an affect on production.
• Machine Cycle Count - machine usage is logged in the table.
• A Software Check is carried out, if a newer version is available this may
contain known defect fixes or equipment enhancements. The service
engineer can recommend an upgrade for the equipment in service. In
addition, the machine event log is checked to identify any re-occurring
errors which if not inspected/diagnosed may lead to unplanned downtime.
• A standard Monthly Maintenance Check consists of a series of mainte-
nance tasks which are performed every month.
Machine safety checks are carried out on a basis as laid down in the monthly
schedule. In addition, the engineer performs maintenance on set machine
modules, checks software version and records the cycle count.
Module 2 In this module, over the course of a year, the following assemblies are checked.
• Printhead
• All Electrical Enclosures
• Camera System
• Squeegee Mechanism
• Rising Table
• Paste Dispenser
• ProFlow
• Temperature Control Module (TCM)
• Screen Alignment
• DC Supplies
• Vacuum Filtration Unit
• Pneumatic System
• Safety System
• Rail System
• Print Carriage
• Machine Level
• Screen Change
• Adjustable Screen Mount (ASM)
• Topside Referencing System (TRS) Option
