Re: all black copies

It sounds like you have a fraed or partially broke wire going to your optic bar.You should inspect and also put an ohm meter on it and watch as you slide your optics back and forth.

When making copies, only a part of the document prints; the rest is solid black.

Solid black in a copy typically means that the scanner is partially blocked. Open the top, where you'd place a sheet to be copied, and examine the small strip that runs down the side (left, most likely). See if it's clear, or if something is covering part of it.
Most copiers don't use the full size scanning plate for copies, but use a strip that scans the paper as it moves across it. If something blocks part of it, you get the black area.

I get a black line when scanning, ( not when printing)how do i fix it

This is commonly caused by a mark on the scanner plate. If you place your document to scan on the scanner plate (Lift the lid and place it on the glass plate) and scan or copy the document does it come out clean? If you feed the document through the Auto Document Feeder doe the line appear?

If when place on the plate it is clean but fed through the ADF there is a line, then when you lift the lid on the scanner you will see a narrow glass plate at the end (Normally the left end) of the scanner plate. Give this glass a clean and your mark will go away.

If the scan or copy is lined when using the Flatbed scanner and the ADF then the problem will be in the scanner lamp which will be probably uneconomical to fix.

Scanning takes an image on a document on the scanner's platten and converts it to a digital file format stored on your computer.

Copying is scanning + printing.

To copy, you do not need to separately scan first and then print. Just select how many copies you need on the number pad, then press either the Black or the Colour COPY buttons on the scanner (or open the printer's/scanner's software and click on COPY), while it's connected to the computer and the document will automatically be scanned and printed (copied).

I hope this helps.

I would like to know if there is a way to recall items previously copied on the Aficio 2022 copier?

The machine didn't store that info.
For all i know no machine make it.
If you had a recent model with HDD, You could stored the document in the document server (a function of the recent models with HDD) and then print the info stored in the HDD

HP Officejet 6300 All-in-one machine makes black streaks

The problem is that that there a small piece of glass that the doc feeder use's to scan the orginal. You will have to clean the small glass it's about a half of a inch piece and is normally under the doc feeder unit. It will either be to the right side of the main copy board glass or it is under the doc feed unit where the paper goes down through the feeder. It is mostly some white out on the glass, just clean with a dam cloth with water or windex..... Good Luck

Scanned Items or Copies all print in Solid Black

I assume that you mean color images are being produced in black and white. If that's the case, there's a document on the HP web site that shows you what to look for and provides solutions:

Color Image Prints in Black and White

Good luck.

Scanned documents are very light

I have found that when scanning b/w documents, its helpful to start with a black and white copy, not a grayscale, pen written, or printed form a printer in grayscale mode copy, but a true black and white on the copier or fax copy. The scanner doesnt read shades of black so well and when scanning multiple page documents, my pixma tends to scan in lightly. I havent found a piece of software to do just this, batch darken what has been scanned (at least not for free). Copying before scanning is the work around. Hope this helps everyone who's had this problem. It also doesnt hurt to darken what your scanning down a notch when copying
