Question about Canon imageCLASS D780 All-In-One Laser Printer
Not the toner cartridge....the print function still works fine. Only copies are blank.
Make about 5 to 10 prints; then, leave the machine in the office environment (normal temperature/humidity conditions)
* This symptom is noticeable in a low temperature/ humidity environment, and is absent under normal environmental conditions.
* This symptom occurs in keeping with the primary charging roller rotation (38 mm).

Possibly sounding silly here, (again) but have you removed the seal from the toner cartridge (This is a breakaway plastic tab, connected to a length on plastic, which seals the toner for transit)
If this has not been removed from the cartridge then it fails in just the way you are describing
