Ladybird Folder
03-Mar-2014
Service Manual
6-7
GENERAL
PROCEDURE
MAINTENANCE
The folder demands activity of cure and maintenance apt to maintain good functionality
and performance.
In order to estimate which type of action is necessary to realize, it’s necessary to know the linear meters
proceeded by the folder and the jam’s frequency , these elements will be able to give you a panorama of
the activities for clean up , calibration and substitution.
Since the paper passage worn out folder parts or path is necessary to verify the expected life for rollers,
antistatic brushes or paper guides.
Before the limit is reached and folder functionality may be reduced it’s important to perform the
maintenance activities and replace these parts near or over the estimated life
When the limit is reached the CSE needs to identify part or components worn out and perform the
maintenance activities.
Here below parts are listed with description of reason and or explanation of relative folder failure
PART REASON
Bushing
Poor shafts rotation, noise
Bearing
Poor shafts rotation, noise
Static Brushes
High paper static load, paper stick on folder guides Poor folding quality
Driving Roller
Poor print transportation, lack of pressure
Rubber rollers
Poor print transportation
Sensors
Poor print sensing, resulting in lower fold quality
Every 15000 meters folded: Maintenance activities Check & Clean
9
Every 60000 meters folded:
Maintenance activities Life Part Replacement
The CSE has to perform other activities every multiple of 15000 and 60000 meters folded.
The folder does not provide a folder life counter, for the operator the folder visualize the number of
copies folded since the folder is switched on, this is only and informative counter, it does not generate
any message or recall maintenance activity.
The identify the number of copies handled by the folder considers all the copies folded, as well all the
prints manually fed and the copies or transparencies bypassed.
The folder counter is erased each time when the folder is turned off, in order to estimate the number of
copies folded read the linear meters printer counter.
The folder after 15000 meter of paper folded needs operations designed for to remove paper dust that
can damage or reduce the folder functionality
PART TASK
All Sensors
Clean all the sensors from paper dust
The pressure of the
Rollers

Cams / bearing /
bushing lubrication
9
Check the cams and lubricate them with grease (use the type of grease
you would use for bearings)
9
Check the bushing and clean or lubricate them with light oil
