Plockmatic LCT3500 Large Capacity Tray
Maintaining Your Machines
Limitations
•
The LCT3500 is suited for customers whose processing needs will not exceed a monthly
aver-age of 200,000 sheets from each tray.
•
The optical double feed sensor should not be turned on when feeding 200 gsm / 74 lb,
covers or higher density paper.
•
When loading paper in the trays of the LCT3500 make sure that it has the same direction
of pa-per curl: paper with different curl directions cannot be mixed, doing so would result
in a misfeed or a jam.
•
For optimum performance in the LCT3500, media shall be stored in a climate controlled
envi-ronment. For media stored in environment with relative humidity over 50%
performance of the LCT3500 may be reduced.
•
LCT3500 might produce pressure marks on lowest paper in the paper pile if media is
sensitive.
•
LCT3500 might show marks from the vacuum belts when running extra thin media. This
issue might occur when using 80 gsm plain and 100 gsm coated types of paper. The
recommended solution to this is that of using MANUAL process settings and to reduce the
vacuum amount. This will reduce / eliminate such marks.
•
When running the LCT3500 with the Ricoh ProC9200 series, the smallest sheet size that is
supported is 19.2" or 487,7 mm in the process direction.
•
When vacuum tray is used in MANUAL MODE, the process position can only be set to 10 or
lower. If higher process position is used, MAX load capacity will be reduced by
approximately 5 to 10 mm.
•
In humid non climate-controlled environments an increased number of double feed jams
has been observed.
•
For optimum feeding performance the paper stack should be "fanned" by the operator
prior to loading the tray. This reduces the risk of double feed from the trays. For more
information, see "Paper stack preparation" under the first section of this manual (basics).
•
The Ultrasonic Double Sheet Detection Sensor does NOT work on all 400 gsm types of
paper, as paper density can vary significantly (900/50 = 1800% in one sheet).
•
The Optical Double Sheet Detection Sensor does NOT work on sheets thicker than 250
gsm.
•
The Vacuum Trays do not always feed the last sheet when running thick media (thicker
than 350 gsm).
•
The Optional LSM might have problems feeding electrostatically charged paper.
•
The Vacuum Trays might have problems feeding the last sheet when processing thicker
media.
•
If the machine is placed under a direct light source, the Paper Empty sensor on the LSM
(Q505) might give false readings.
•
If the machine is placed under sunlight, even through a window, the five cork plates
located under the feed roller will wear quickly. This will result in an increased number of
double feeds.
