Question:
I've been following your videos, which have benefited my L1800 model in the DTF printing journey. I just changed the waste ink pump; now my printer won't print. It has no warning lights, and I've checked the printhead to verify it's not clogged. Help me identify the issue.

It seems that your printer can have a cause of several things to it, as before you had the waste ink pump replaced. The top causes and solutions are provided below:
1. F1 Fuse Issue
If the mainboard powers up but no ink is ejected, the F1 fuse in the Mainboard has blown. Even when the printer runs as usual, a fault in the fuse will prevent it from processing images. The recommendation is to check and replace the F1 fuse if it has blown.
2. Driver IC Chip Failure
Driver IC Chip. This is also likely. The same chip controls the voltage supplied to be directed onto a printhead. If it is not working, the printer may still try to print, but in some cases, this can mean that the Printhead does not get enough juicy juice (whatever voltage it needs), which leads to no ink being ejected. The IC chip needs to be tested or swapped out.
3. Q601 Chip Problem
If the mainboard does not even turn on, the Q601 chip can be broken, or the printed head will no longer function properly. If the mainboard is turning on but has no printing, you may need to test and replace this chip.
4. Capping Station Malfunction
Based on your description, the capping station is most likely not sealing around the printhead. This may be occurring due to a priming issue with the printhead. A proper seal is required to prevent air from blocking ink flow from the printhead. To verify and correct this, you can do the following:
Pull from the waste line before parking your printhead at the capping station. There should be no contract on your end. If so, then the capping station may be jammed or misaligned.
I recommend some of the video guides because they are straightforward, such as how to fix a capping station (Capping Station Fix) (https://youtu.be/RVtQLe2wTsk) and the additional capping station guide.
(https://youtu.be/_cZEkmgIZYc).
When the capping station is repaired, you will need to prime the printhead using this guide —
Correct Printhead Priming Process
Important point: Do not power clean after installing a new ink system, e.g., conversion nipple printhead and dampers—use the following steps instead to prime it:
Step 1. Power Cleaning is built to solve print quality problems and requires a lot of ink (which is not good to load). Epson says to wait about 12 hours between Power Cleanings, as using them too often can waste ink.
Step 2 — How To Properly Prime The Printhead
The Printhead Some models of the R260/265 and RX580 have been known to sit better overnight, so if you have a rest problem, see what happens after sitting for some hours; otherwise, try parking at the capping station manually by turning on the printer.
Draw Air with a Syringe: Fix the syringe to the waste tube and pull 3 ml of air. This will make the pressure more equalized and suck ink into the printhead. Watch this step on my YouTube video at (8:00): https://youtu.be/_pyLQsfn4mQ
After priming, perform a regular cleaning cycle (non-Power Cleaning). This should flush ink through the print head nozzles and get your printer working again.
Step 3: Monitor the Ink Flow
Test for the ink flow on the waste line after priming. Even after trying, if you continue to get blank prints, the problem might be more severe and related to something linked through the printhead or mainboard. In this situation, we might need to dig deeper and check if all the pieces work end-to-end.
Additional Tips:
If you print often, I recommend performing a heavy clean at the start and end of each day for general printer maintenance. However, you must never prime your print head using this cleaning. Instead, go for regular cleanings to keep the printer working well without using too much ink.
The white ink channels are quickly clogged, so check them as well. WHY DOES THIS HAPPEN? Watch this informative video on white ink channel clogging and prevention: White Ink Channel Clogging (https://youtu.be/Ey3wsy9V4zs). Cleaning after every few designs/feet of printing will keep these issues at bay.
The problem with printer issues is that you must be hands-on in almost all cases. Sorry, but we do not troubleshoot or provide remote assistance for printer repair. However, we provide in-person diagnosis and repair service locally (https://bchtechnologies.com/printer-repair-service). Repair is first come, first served; it could take weeks before your printer can get into the queue. Mail-in service with instructions is also available.
If you need more DIY, check our YouTube (youtube.com/@bchtechnologies) and search for specific videos with the magnifying glass icon. Unless you are always looking for new material, there is a good chance that you can go through suitable tutorials here with more than nine years of content archived. Following your search and discovery can lead YouTube to offer up other videos based on your interests or needs that align with what has been enjoyed recently.
Thank you again, and I hope this helps get your printer back into action!
