General Maintenance Issues
.
Due to the printer's size, when performing any service or
maintenance operations, confirm there is plenty of space
for the operation.
Due to the printer's size and weight, make sure any area
you move the printer to or any surface you place the
printer on is stable.
Since the EPSON Stylus Pro 7000 is quite heavy
(approximately 43.5 Kg for the printer body plus another
8.5 Kg for the stand), be careful when handling it. When
separating or setting up the printer body and stand, you
need two people.
When removing parts, ink may drip on the floor or lower
sections of the printer. Therefore, spread a sheet or
similar object when removing ink-related parts.
When handling the electric circuit boards, do not touch
the elements on the board by your bare hands to prevent
the elements from being damaged by static electricity.
Wearing an earth band is highly recommended.
If it is necessary to turn on the printer after removing
various covers, be especially careful around the carriage
and fans to avoid injury.
Keep in mind that the cutter blade is made of very hard
material and may easily break if it contacts metal parts.
If the printer needs to be transported for any reason, refer
to Chapter 9 of the Users Guide to put the printer into
printer-transport mode. Also, only use original packing
materials and pack the printer as shown in the Start-Up
Guide or Assembly and Setup Guide.
