Please Help!
Roland VS-640, brand new Roland ink cartridge, but the printer still senses it as empty. The cartridge itself is recognized that it is installed, but the ink level on the printer's LCD remains zero. We updated the firmware: nothing. We tried different new ink cartridges (with their new IC chips) without any success. The local Roland service replaced the Ink Tank Board, the Cartridge IC Board, the Cartridge Holder Assy, but the error is still the same. The local service practically gave up, they want us to discard the printer. It is 6-7 years old but barely used, almost like new, so this is not an option for us.
I would need help in the following topics:
1.) Is there a reliable Roland Service that can diagnose and finally solve this problem? We are in Largo, Florida.
2.) Could somebody explain the the exact way this printer senses and registers the ink level?
As we understand, the cartridge pushes a micro-switch (called "Ink Cartridge Sensor") that senses the installed cartridge itself. The cartridge has a white plastic tab on its side that comes out when the ink level is close to zero. The tab pushes the "Ink Empty Sensor" that detects whether the cartridge is empty or not. The chip on the cartridge communicates with the "Ink Cartridge IC Sensor" to make sure that the ink is genuine Roland ink.
In our printer, all the above hardware elements were replaced by the service. Even the cables with the MOLEX connectors are new. It seems that somewhere there must be a memory that keeps the calculated ink level that should be reset by a new cartridge chip. If this memory value is "empty" and cannot be reset to "full" the printer won't work. Where is this memory if not on the Ink Tank Board? On the Main Board? Somewhere else? What else can be wrong? It seems impossible that a Roland printer cannot be repaired if it is 6 years old.
Sorry about the lengthy post.
Any help would be really appreciated!!!
