[Misc] Blurry text in spots 951

[Lx5]

the problem is at the morning. when the customer turns on the machine, the first 100-200 pages are blurry like the example and after that,this symptom never occurs again till the next day. I did change drum,developer,charging (because of maintenance) and the symptom still occurs. It only stops if i clean the drum with isopropyl alcohol. I also did clean the discharge but nothing changed. Any guesses?

The example is before the cleaning the drum and after cleaning it. The background of the tabs also missing before the cleaning and it never happens on the same spots. Its random.

Is drum issue.
Το τύμπανο θα άλλαζα πρώτα! Υπάρχει και μια επιλογή στο adjustment drum sensitive recall, πες τον πελάτη σου να κάνει αυτό κάθε πρωί και να δει πως θα πάει! Μετά αν δεν στρώσει να αλλάξεις τύμπανο!

What sort of environment is the machine kept, and why are you turning it off?

I suspect condensation on the drum, as a result of high humidity or low temperature, or both.

High humidity environment. Leave machine on so dehumidifiers can do their job. We see this at the beginning of the school year on at least half our 951's from the machines sitting powered off all summer.

I was thinking for humidity too but this happend also at summer. To be honest, at summer, is way more blurry than winter.


Thank you all guys for the informations. I will let you know when i try them.

Around here, it's way more humid in summer than winter and that's when we always had issues with humidity in paper. Now, humidity doesn't cause issues nearly as bad as it did decades ago on analog machines, with all the improvements in the systems.

That's right, high humidity is culprit. Do not turn OFF mains supply and internal heaters keeps humidity in control.
