Read the paper fields exactly
RevF’s paper-specification table lists a maximum roll outside diameter of 83 mm and spool inside 12 mm/outside 18 mm. For 80 mm-width operation it lists actual paper width 79.5±0.5 mm;for 58 mm operation,57.5±0.5 mm. These are the named model’s fields,not a specification for every receipt printer.
Separate wound width from paper width
The same table separately lists width when wound:80+0.5/−1.0 mm or 58+0.5/−1.0 mm. That distinction prevents a nominal size label from being treated as an actual measured paper width. Our source finder retains the two configurations separately and does not decide an installed configuration from a roll photograph.
Thickness and grade are still required
The current thickness field is 53–75 micrometres. It also names specified original paper types and links certified media information. Supplier 58 gsm wording does not satisfy this thickness field by conversion,and none of our selected carton records establishes every required exact grade and spool dimension.
Use a reference,not a fit verdict
Use these values as a manual reference while gathering the missing product evidence. They are not a declaration that 3758B,TTR001 or 102 is approved. No physical fit,sensor,cutter or print trial was performed,and any unresolved field should be clarified with the current exact source.
Apply the field to a purchase
For the current 53–75µmfield,53 and 75 are stated bounds,not an instruction to round an unverified product thickness into the interval. A missing product value stays missing even when itsgsmlooks plausible.
