c2557 error on Konica c252 color printer στους 10 βαθμ Κελσιου / 85%υγρασια
Οταν ανοιγεις τον διακοπτη ξεκιναει τους ελεγχους φουρνου, ιμαντα, οπτικου, και μοτερ
μετα ρυθμιζει την ποιοτητα των χρωματων, και προσθετει τα αντιστοιχα χρωματα,
οποτε και δινει ετοιμο…και σταματανε ολα τα μοτερ….εκτος τα Fan (η κανονικη διαδικασια -ζεσταμα…)
c-2558 yellow sensor... also set new Pcu, supplies toner continous… and stop… clean scanner glass, no. maybe CB MAIN BOARD fault. koskN
- αν ομως κατεβαζει σχεδον συνεχως μαυρο τονερ(γυριζει περιοδικα το μοτερ…)
- με αποτελεσμα να μαυριζει λιγο -φοντο το τυμπανο αλλα και σκονιζει ο τρανσφερ ιμαντας…φοντο απαλο σκονισμα
και μετα απο 4-5λεπτα δινει τον κωδικο

- δεν εχει ΜΑΥΡΟ toner ? τέλος γραφίτη;… αλλά εχει κ γνησιο …/
- όχι όλο το σύστημα προσθήκης γραφίτη Λειτουργεί κανονικα… μοτερ γραναζια καταβοθρα…
- Με αλλαγη με γνησια νεα καινουργια μοναδα IU-K = το ίδιο
- όχι η υψηλη ταση- πλακετα HV την Αλλαξα,
- όχι TR Belt τον Αλλαξα και το ιδιο…
- ζεσταμα με σεσουαρ ολες τις γραμμες καλωδίωσης υψηλης κλπ πισω.
- να πω οτι ειναι η Κεντρικη?.. για αλλαγη PCB, η το Main CB… ή …τι;
- ΕΒΑΛΑ ΛΟΙΠΟΝ Μονωση χαρτοταινιας … στις επαφες της Charge, …Grid, …Bias…. αλλα παλι φορτιζε το τυμπανο…
- παμε στο βιβλιο λοιπον…. τι φορτιζει το τυμπανο?… τραβαει ακομα ΚΑΙ σιδηρο… Πως ειναι δυνατον αυτο???
Απλά Στην εκκινηση ρυθμιζει τα χρωματα και ….ζήτησα την γνώμη 5 τεχνικών…
Στο γιατί *φορτώνει μόνο Μαύρο χρωμα* Ιμάντα+Τύμπανο μαύρου…. Αυτό είναι το θέμα….
Μήπως δεν ξεφορτώνει… Το τύμπανο? Πώς το κάνει? Engine PCB?
