Open the cover underneath the ink tanks to expose the filters and pipes running to the carriage. Open the cover on the railing that houses the ink pipes along the gantry. As a precautionary measure put the dampers inside a container as they might leak during the process.
Cut off the ink pipes just after the filters and use a cigarette lighter to seal off the ends. To make the process of removing pipes easier remove the clips on the trunking. You can proceed and pull out the pipes through the carriage board compartment on top of the actual carriage.
The next step is feeding the new ink pipes through the gantry. Separate the pipes into 2 sets of 4 and use tape to hold them together. To protect the pipes as the carriage moves run them through the sleeve provided. Once done put back the clips on the trunking and feed the rest of the pipes all the way to the tanks. Screw back the cover for the railing that houses the ink pipes along the gantry.
Dispose all the old ink from the tanks. It is of importance to thoroughly clean the tanks, filters and pump before putting the new ink. Where possible the filters/pump can be changed.
- The first step is to clean out all old UV inks using old UV cleaning liquid
- Flush and rinse using new UV cleaning liquid least twice
- Connect the new pipes to the filters
- Pour the new premium UV inks to not more than 50% capacity making sure you shake first
A DX5 printhead is an 8 channel printhead which works with the following damper sequence: KKCCMMYY. Since 4 pipes are dedicated to each printhead there is need for 4 Y connectors to split each channel into 2. Use of negative pressure dampers is advisable as they withstand pressure better eliminating the problem of ink dripping through the printhead. Use a syringe to gently pull ink into the dampers and place them in the order KKCCMMYY. Since Y connectors are used fold the right-hand pipe such that it’s airtight then pull ink into the left-hand damper. Once done repeat the process to pull ink into the right-hand damper whilst folding the left-hand pipe.
Perform a manual pump for a few seconds followed by a head clean. A nozzle test with 2 blocks of each colour is confirmation of a successful ink conversion. The printer will then be ready for printing.
