EPSON Stylus Pro 7500 Revision A
Troubleshooting Troubleshooting Based on Error Display 80
WARNINGS
Warning messages appear on the LCD display to warn users that a problem may occur. The
printer can still print and there is no effect on print quality; however the messages do not go
away until the possible problem is taken care of or the printer enters the corresponding error
condition. For example, the Waste Ink Pads Near Full message will remain until the pads
are replaced and the counter is reset or until the pads become full and the printer enters an
error state.

ERRORS
Error messages appear on the LCD to notify the user that the printer cannot print properly
under the current conditions. When an error message appears, printing stops and data
transfer from the host PC stops. (The parallel interface signal = /ERROR -> “LOW” and
BUSY -> “HIGH” and data cannot be entered.)
Table 3-4. Ink Low
Item Description
LCD message INK LOW
LED indicator
status
The LED indicator for the ink cartridge that is low flashes.
Details
If the standard 100 cc ink cartridge is installed:
The printer detected that the soft counter for one of the ink cartridges was at
Near-End. When the soft counter’s Near-End signal is generated, it means
that the cumulative number of dots is counted by software, and that the
remaining amount of ink has been calculated to be less than 10%.
After Ink Low is displayed, it means, as a criterion, that the area of an A1
sheet can be printed with 100% duty, but the ink cartridge should be
replaced as quickly as possible.
When replacing an ink cartridge, a new cartridge which is full of ink should
be installed. (A partially filled ink cartridge that has been removed should
not be installed a second time.) If this is not strictly observed, the correct
operation of the remaining ink indicator cannot be guaranteed.
If the large capacity 200 cc ink cartridges are installed:
The printer detected the Near-End signal for one of the ink cartridges. The
Near-End state is detected by the position of the sensor plate inside the
cartridge, and judgment made. After Ink Low is displayed, as a criterion, it
means, as a criterion, that the area of an A1 sheet can be printed with 100%
duty, but the ink cartridge should be replaced as soon as possible.
When replacing ink cartridges, a new cartridge which is full of ink should be
installed. (A partially filled ink cartridge that has been removed should not
be installed a second time.) If this is not strictly observed, the correct
operation of the remaining ink indicator cannot be guaranteed.
Recovery Replace the old ink cartridge with a new one.
C H E C K
P O I N T
If it is necessary to replace the ink cartridges before Ink Low or Ink
End is detected, and when replacing all the ink cartridges with new
ones, the counters should definitely be reset.
Reset the counters by “Maintenance Mode 2” -> “Counter
Initialization Menu” -> “Ink Initialization.”
