Overview: Canon PRO-1000 users in Japan have encountered an issue with error code 1752, prompting the need to replace an ink cartridge even after a genuine ink refill. This problem is linked to the printer's ink level detection system, and users seek to disable it for successful refilling without errors.

Disabling Ink Detection: Upon encountering error 1752, some users suggested holding the Resume Button for 5 seconds, which can sometimes resolve the issue temporarily. However, this method may not provide a permanent solution.

Error Code Differentiation: Canon JP clarified the distinction between error codes 1752 and 1730. Error 1730 results from a disparity between the recorded ink level on the IC and the actual ink amount. The printer's unique platform and state transitions contribute to these error codes.

Disabling the Chip: A user advises disabling the chip to eliminate error codes 1751, 1752, and 1730 permanently. Once the chip is disabled, the printer allows refilling without triggering these errors. However, caution is urged as running out of ink can lead to potential issues like nozzle reassignment and printhead memory depletion.

Printhead Memory Considerations: Canon PRO-1000's printhead memory has a finite number of nozzle reassignments. Running out of ink can initiate reassignment during maintenance cycles, potentially leading to a B2XX error when the memory is exhausted. Regular usage is recommended to maintain optimal printer behavior.

Cautions and Best Practices: Disabling the chip requires careful consideration. Overusing the locking mechanism to check ink levels can lead to its failure. Additionally, continuous printer use is recommended to prevent potential issues associated with infrequent printing.

User Queries and Recommendations:

1. Clogged Nozzle Detection: Users inquire about the PRO-1000's ability to detect and reassign nozzles during cleaning with no ink left.
2. Error Codes B200 and B203: Concerns are raised about these error codes during printer repairs, highlighting potential issues with head burnout and flexible cable short-circuits.
3. Printing Frequency: Emphasis on regular printing to prevent issues; a query about checking cartridge levels during refilling.
4. Ink Source Alternatives: Users explore alternative ink sources, such as PFI-700 series inks, and seek advice on compatibility and color matching.

Community Insights: Community members share experiences with PFI-101 ink and discuss cost-effective options for ink procurement, especially in the Japanese market.

Summary and Recommendations: In summary, when encountering error code 1752, topping up the ink and replacing the cartridge can temporarily resolve the issue. Disabling ink monitoring is advisable at this stage, but caution is essential to prevent potential nozzle and printhead issues. Regular printer use and careful handling of components are crucial for optimal performance.
