Clear print logs via factory reset and improve log overwrite system

This is mainly for privacy-conscious users who encounter a print issue and need to submit a log to customer support.

According to my testing, the printer logs up to 39 hours of print data. Factory reset does not clear logs, and older print jobs remain logged until internal storage limit (700MB I believe?) is reached.

Vote for solution below

  • Let the user reset the printer internal storage via factory reset, overwrite logs at the beginning of each print, and reduce log storage limit by at least half.
  • I have another solution (comment below)

I use winscp to connect to my P1P and copy the log files that I want to submit. I can also delete the older files. I could also remove the SD card and put it in my computer to manage logs.

My experience (on the X1C) is that WinSCP only shows SD card contents, not the printer internal storage. If you don’t have an SD card plugged in, it’ll show you an empty /root directory. So you cannot clear the logs stored on the printer’s internal memory. Please remove the SD card from your P1P, then open WinSCP and see if there’re any files there. Maybe P1P’s FTP connection behaves differently, in which case BL should fix the X1C (I doubt that).
The only way I can see to get the log from the printer to the SD card is to press the “Export log to MircoSD Card” button on the LCD screen. This does not let you manage the log, you don’t have control of the time frame exported, it simply exports the entire archive (all 39h).
I’m not sure how you “manage logs” on your computer when the exported log archive is encrypted?

I forgot about the difference. The P1P does not have internal storage for such things. It must have the SD card inserted to work.

The X1C, on the other hand, updates logs even when in sleep mode… You can see how this can be a bit concerning.

I am pretty sure that i read in the docs that logs were limited to 600MB. I wonder it that would apply to the X1, and if it has a different algorithm to rotate logs given that it can use memory instead of an SD card.

Logs are limited to 600-700MB for the P1P according to BL. On the X1C, when you export a log it says on the screen that logs can be around 1GB. My 39 hour estimate is based on the more conservative 700MB max log size that really applies only to the P1P.

Regarding the algorithm on the X1C, let me clarify my findings:

  • In sleep mode, logs are recorded at a rate of 0.1MB/minute
  • In print mode, logs are recorded at a rate of 0.3-2MB/minute (imprecise because I’ve not done many prints yet, being more concerned that it’s apparently recording data when in sleep)
  • Logs stored on the printer’s internal memory are overwritten only when storage limit is reached (whether it’s 600MB/700MB/1GB I do not yet know)
  • When this limit is reached, logs get overwritten in chronological order (starting with the oldest) - this I cannot confirm without breaking encryption, but any other way of overwriting logs wouldn’t make sense
  • An exported X1C log is simply all 39 hours (including sleep mode information) dumped into a single encrypted archive which you cannot open or edit in any way
