Thank you for contacting us! We truly apologize for not responding to you sooner. Printer problems have a certain sense of urgency, and we know how agitating it is when a piece of equipment doesn't perform as it should. You read that our responses are pretty detailed, and behind every question, we take it seriously. We are honored to have you with us on our YouTube channel (BCH Technologies on YouTube [https://youtube.com/@bchtechnologies]).

Now, we can finally deal with the problem you are having pain with related to the ink in your CISS not moving. However, the underlying problem is the peristaltic Pump, the most crucial element of the system. Here's a step-by-step guide on how to diagnose and fix this issue:
 
Verify Voltage with a Multimeter:
You can check the peristaltic Pump with a multimeter starting from its voltage. CISS Most CISS systems use pumps that run on 12V or 24V.

• While powered on, measure the Pump by attaching the multimeter probes to the pump terminals.
• Is the voltage compatible with the pump specifications? If not, there may be a problem with the power supply or the control board.

Inspect the Pump Mechanism:
So, assuming the voltage is correct, we can disassemble the Pump.

• Check for blockage caused by wear and tear or damage to the internal parts, like the rollers or tubing.
• Disassemble the Pump well, then completely clean it to remove any clogged dried/thickened ink.

Test the Pump's Operation:
Clean and inspect the Pump before reassembling it. Then, connect it back to the system to test it, making sure the ink flows smoothly through the channels.
 
If it is, it may be necessary to replace the Pump:
Otherwise, if the correct voltage is provided and the Pump is cleaned as directed and doesn't pump, it will likely be replaced. Typically, replacement pumps can be found from printer part suppliers or CISS-dedicated retailers.
 
However, this is tricky to solve as printer problems are hands-on affairs. That is to say, we cannot offer to troubleshoot, suggest, or repair printers remotely. We do an on-site diagnosis and repair by our local diagnostic center (https://bchtechnologies.com/printer-repair-service) and operate on a first-come, first-served basis since they are heavily in demand. You won't be able to drop off your printer immediately, though; it may take a few weeks. We regularly organize our work so only the whole printer will be repaired, and specific parts will be repaired from top to bottom so the reader knows what happened during the process. Yet we understand that our rates are not the cheapest.
 
If you are looking for a DIY solution, we suggest you start with some online resources. Visit the web home of our YouTube channel (BCH Technologies on YouTube [https://youtube.com/@bchtechnologies]) and search for topics using the search icon. With nine years' worth of material, this is our fastest means of finding relevant videos. YouTube might also recommend helpful videos made by other creators.
