If the main window is opened while the printer is doing something, be it a swath of a print job or a
system task, the printer will:
1. Before the carriage stops, it will finish whatever it was doing when the window was opened. It will
not finish an image it was printing, but it will finish the current swath, so as to avoid any impact
on image quality. If it was performing a system task it will finish it before stopping.
2. If the carriage finishes on the left side of the printer, the carriage will always slowly move to the
right side of the printer.
3. The printheads will be placed in their 'capping' positions.
Here are some different scenarios of what happens when the window is opened:
●
If the printer is printing an image when the window is opened: The carriage will not stop
immediately, the printer will finish the swath and then stop. If the cover is then closed, the printer
will start to print from the position it was stopped.
●
If the printer is cutting the media: The carriage finishes the cutting procedure.
●
If the printer is checking the SKEW while loading the media: During the skew check, the printer
does small movements of the carriage on the right side of the printer, and also moves the media
when needed. This procedure checks that the edge of the media is moving laterally or not. If the
window is opened while the printer is checking the media SKEW, the printer will complete the
skew procedure (and it will continue well after the window has been opened). This is the only case
when the printer will not stop the carriage at the end of a lateral movement (as a swath).
The safety system in place is designed to detect an object in the path of the carriage as it moves across
the printer, any object encountered will cause the system to shut down the driver motor in the carriage.
This method of ensuring safety is considered sufficient by the regulatory agencies that inspect and
assess the product prior to its placement in the market. The window and its switch are considered a
‘supplementary’ safety feature, and as such the behavior of the switch has been adjusted as a trade off
between the level of safety provided and the printer’s functionality.

Troubleshooting based on symptoms
Introduction
The System error 79:04 is a generic firmware error (equivalent to a blue screen in Windows). It’s the
System Error that the printer will display when an unknown exception occurs that cannot be pointed to
by any specific subsystem of the printer.
Since this is a generic error, there can be multiple causes behind it. This document will cover the most
probable causes behind a system error 79:04 and will recommend the most efficient troubleshooting
steps to resolve customer issues.
One important point to mention is that, although 79:04 system errors can be caused by a hardware
malfunction, the vast majority of 79:04 system errors are pure software or firmware issues. In these
cases the issue can only be solved by determining the root cause and implementing a solution. The
solution can usually be applied by either correctly configuring a selection, updating the printer’s
firmware/software that is being used or by fixing an error in the code).
