Well, I'm sure it is one of the standard size fans. And I'm sure once I disassemble the unit I should be able to measure it and order the right one, let say from xxxegg. But it would mean I will have to either do the disassembling twice or have the printer in non-operable state for some time(until the new fan arrives)...
No, I do not want to have the fan switched off using an external switch (that would be to easy and I would not even ask for help here
)
And also if I remember correctly according to the maintenance document there are some error codes associated with the non-working fan, so it should be a 3-wire model...
I'll wait for a few more days to see if anyone has some knowledge on the type of fan I (we
) need...
Some additional thoughts...
When the printer is plugged in but not booted the fan runs at a low speed (and with tolerable noise level).
Once the printer starts booting and until it shuts down the fan runs at a much higher speed (and makes much more noise).
I do believe it makes perfect sense to reduce the fan speed down to the lowest once the printer enters the sleep mode and increase it back to normal (required) once it wakes up for maintenance or for printing. It should be a matter of firmware upgrade and it should be a very easy one(two extra lines of code - one in "sleep enter"; one in "sleep resume"). Does anyone have any means to push HP for a firmware release where this logic is implemented?
