Cdr20 drawer is jammed ERROR message

That means there is something wrong with the mechanism of the CD. The best thing you can do is look inside and see if anything is damaged or stuck in the CD unit. If the drawer doesn't come out at all, it could be that the belt that makes it move is off or broken. I should imagine that could trigger that error message.

The above comment is complete and utter nonsence !
Here's what you do . Take the lid off , take off the top of the cd transport marked "CD 1 Low Jitter Compact Disc Transport" held on with 2 screws , rince it under warm water (its made of plastic) and refit . Its a build up of dust . Yoy will have to do this every 2-3 years . P.S Leave on "stand-by" because you will do more damage to the circuit boards by cutting the power continually .

If job prints from the wrong tray or on the wrong paper or specialty media, this is an indication that the operator panel menu settings do not match the media loaded in the tray.

Make sure the Paper Size and Paper Type specified in the printer driver match the paper size and type in the tray.

OPC means the unit had trouble Optical Processing Calibration, which means the disc surface may be damaged. Using brand name media and being careful to not touch the recording surface would help.

It's not completing the finalization so it won't play in a CD player yet.

It's mostly in the manual

OPC: Stands for Optical Processing Calibration.

When you see this message in the Information

Display for the Record DeckK, it means

that the laser transport inside the unit is making

the calibrations and adjustments needed so that

the recording process is optimized for the specific
disc in use.

When an unfinalized CD-R or CD-RW disc is

placed in the Record Deck%, the letters

OPCwill flash once the Table of Contents has

been read. This indicates that the unit is optimizing

its circuits for maximum compatibility with

the specific recordable disc in use. the number

and total running time of any tracks that have

already been recorded will appear in the

Information DisplayK, and the appropriate

indicator SPwill light to tell you if a CD-R or
CD-RW disc is in use.

To Finalize a disc, place it in the Record

Drawer%. Once the disc's Table of Contents

information has been read and the OPC process

has been completed, press the Finalize button

E@and note that the Finalize Indicator

Uwill begin to flash. Within three seconds,

press the Select button9*and note that

the Finalize IndicatorUwill stop flashing.

The Finalization process will take up to two

minutes, depending on the length of material

recorded on the disc. During the Finalization

process the Record Deck will not accept any
operating commands.

sounds like something has jammed in the drawer track
on the front of the drive is a very small hole
that is the manual open override
use a paperclip and push it into the hole as far as needed until the drawer opens
then slowly open the drawer by hand
look on both sides of the drawer to make sure there is no dirt or other foreign matter in the tracks where the drawer opens

The 'static' is the unit's error detection, -correction and -concealment strategies being exceeded so it puts out the best digital-to-analog translation it can come up with.

You could prove that by playing it on another player and if you get a non-identical result (for example, it starts making the noise at exactly the same point) the data may be marginal but the player's abilities may differ.

If it IS exactly the same, the data is certainly corrupted.

I'd suspect the media. Is it name brand or CD's-r-us cheapo media?

You need to finalize the disc for players to read it.

Buy a new one!!

You need to open it, lift two tabs at the back of the tray on each side to allow you to remove it, then re-insert making sure it's back on the rails.
