ADF duplex scan margin copying

[Alexanderth]

Hi,

Ever since I bought the printer/scanner, I've been having issues with the ADF 2-sided original scanning to pc.

Every second page (backside) has an error on the bottom margin of the document, as it generates the same margin as the bottom of a previous sheet scanned in the batch. Example (12.3 mb below) pg142 as a margin from pg136, pg146 has the margin of pg 136, Etc.

At first I thought it was because that sheet might have been stuck in de feeder, but after removing all the papers after their scan, the issue remained in the batch with the margin of the removed sheet(s).

While writing this topic, I checked the results of the scans I've been making today and it seems to be a size issue.

Error starts on page 8 of a 24 page document. 10.9 mb

Error starts on page 8 of a 18 page document. 11.6 mb

Error starts on page 6 of a 36 page document. 12.3 mb

Error starts on page 4 of a 32 page document. 13.0 mb

And I even went from 300 dpi to 200 dpi to reduce the size, but the issue remains.

The 18 page batch has the error on page 12, instead of 8 with a size reduction to 5 mb.

As there is no suitable option at the moment to avoid this issue, is there any workaround or update available?

Also have to mention that for the uneven pages, the size makes no difference.

Thank you in advance.

Kind regards,

Alexander

Never mind... Seems to be a Embedded Web Server issue.

While searching for firmware updates (even when the printer says it's up to date), I found an OCR update for the HP Scan app.

This app seems to do the job correctly on the scans, but OCR is unfortunately not a searchable pdf.

Am I missing out on more stuff?
