Resolving Persistent Clogging Issues in L1800 DTG Printers

In recent discussions within the printing community, users have reported persistent clogging issues, particularly in the Magenta and Black channels of the L1800 DTG printer. Despite efforts such as multiple power cleans and damper replacements, the problem seems to recur within a short timeframe.

Diagnosing the Problem: Age of the Head and Cap

One user seeking assistance in the online forums revealed that the printer head is relatively new, around 5-6 months old, while the capping system might be considerably older due to the purchase of a used printer. This information is crucial in understanding the potential sources of the recurring clogging issue.

Ink Flow Anomalies: Manual Flushing vs. Printing Performance

Upon manual flushing of the printhead, the user noted the absence of clogs. However, ink flow through the printhead appears compromised, requiring multiple cleaning cycles to manifest in the nozzle test. Subsequently, the ink disappears abruptly, leaving users puzzled about the root cause of the irregular ink flow.

User Insights: Shared Experiences and Possible Causes

In a collaborative exchange, a user named Chetan B shared a similar problem encountered with an Epson R3000, specifically in the yellow channel. The issue exhibited intermittent clogging that would seemingly resolve after multiple cleanings, only to reappear during the printing phase.

Chetan B speculated that the problem might be related to the carriage that moves the print head. Over time, this component could deteriorate, leading to the misalignment of the print head and causing erratic ink flow. Notably, Chetan B suggested reading an article on the topic, offering to share a link for further exploration.

Potential Solutions: Addressing Printhead Alignment and Dampers

Considering the shared experiences and insights, it appears that a misaligned carriage could be contributing to the recurring clogging issue. Users may want to investigate the alignment of the carriage system and explore solutions to address any deterioration that may be affecting the horizontal positioning of the print head.

Additionally, given that damper replacements have been attempted without a lasting resolution, users might consider alternative dampers, such as the DX7 dampers, as part of a conversion process. The transition to a pressurized system, as suggested by NikkoDTG, could also be explored to enhance ink flow stability.

Further Resources

While the exact cause of the persistent clogging in L1800 DTG printers remains to be definitively identified, the insights from user experiences and Chetan B's suggestion regarding carriage alignment offer valuable avenues for investigation.

For those seeking more in-depth information and potential solutions, Chetan B has generously offered to share an article link. Additionally, users are encouraged to follow the BCH Technologies YouTube channel for video content and explore their tech blog for regular updates.
