Several folks at the Northumberland Photography club (NPC) including myself, were having problems when their images appeared very small when projected at club events. As well, some Windows users were not able to detach imbedded images sent by Mac Mail Users. This depended on which version of Outlook the Windows users had. Mac users can get around this problem using the following instructions:Mac Mail to Windows User Instructions

I have been experiencing performance issues (5 – 20 second delays) with Lightroom 2 grid view when editing 20- 30 MB images across the network. My conclusion is don’t use LightRoom across a network, and connect the drives using eSATA instead of FireWire 800.
My Findings:
I use a MacPro to connect via an internal gigabit LAN to a server with a MyBook external hard disk (connected with FireWire 800) . At first I suspected issues with the server, then the network, but now I believe its just the accumulated inherent speed of all of the components. The largest bottleneck seems to the Firewire 800 with its maximum throughput of 100 megabytes per second.
When copying 286 GB of images from a MyBook, I measured overall throughput as 62.6 Megabytes (MB) per second. The copy was taken over a 1GB network between the two Macs.
Although that is not bad, the copy took 72 minutes. Given that a MyBook II supports eSATA this may be wise configuration enhancement for the future.
Measurements were taken using Apple Monitor.
The hardware configuration is as follows:
- Server Mac Mini – 3GB memory, 2 Ghz single Intel Core 2 Duo. (Macmini3,1)
- WD My Book Studio Edition II – 4TB - configured as Raid 0 – striped across 2 – 2TB drives, connect to the Mac Mini using a FireWire 800 cable.
- MacPro – 8 core. 10GB memory.
- Dlink DGS-1008D 1 Gigabit switch (1000Mbps)
One of the bottle necks seem to be the maximum speed of the FireWire bus transfer – in this case 100 MB per second (800 Mb/s). I also suspect the bus speed of the Mac Mini bus but have no way to measure that. Click thumbnail for larger image.
Both memory and CPU have been ruled out as a bottleneck so that left the network, computer bus and MyBook. I will test the local connection and report my findings.
Just got a new Epson printer – 13 x 19 inch paper. I am pleased with the quality but it jams about 95% of the time when using large paper in the single sheet feeder at the very back. After waisting a lot of paper ($69 for 20 sheets) I finally called Epson.
They were reasonable, after 42 minutes on the phone they suggested I return the printer for an exchange. OK – so lets see if they live up to their word.
PS – since I don’t seem to be the only person to have this problem, you can also see:http://ryan.bigwoofs.com/2009/12/epson-r1900-paper-jams-with-velvet-fine-art-paper/

Jan 20 – Epson called and stated they were sending me a new printer. I will test it and see if it has the same problem and report the findings here.
Jan 21 – printer arrives – will test it tomorrow
Jan 22 – Exact same problem. My conclusion is that the Velvet paper texture causes the to falsely pick up a printer jam when in fact there is none. Wish Epson could have identified that.
Here is the only method of loading the paper in the manual paper feeder that hangs off the back of the printer:
1) load paper until printer grabs it.
2) Print from computer
3) 95% of the time the printer will jam – on the printer, press the blinking paper light, the printer will eject the paper, wait for this to stop
4) Press the paper button again
5) Push the paper back into the printer – keep a small amount of pressure on top of the sheet until the printer starts to print. Be aware that the paper will move back and forth in the rollers – just gently keep the pressure on.
Jan 26 – Kudos to Epson they solved it sometimes. I reported the above and they called me back today. This time I spoke with someone very knowledgeable and they said the printer checks that the paper is in straight and if it isn’t then reports a jam. Its very sensitive and somehow the Velvet seems to be more problematic.
To solve the issue, ensure the paper rests snugly against the right side of the printer and when the printer grabs the paper, it continues to rest against the right side of the paper guide and is perfectly straight.
It solves the problem sometimes, but mostly I just gave up and put the paper into the single sheet feeder and don’t have any issues.
PS – If after all of the above you forget which is the printable side of the paper: Stick the corner of the paper in you mouth. The side that sticks to your lips is the printable side.
Jan 27 – had about 80% of 13 X 19 inch semi-gloss jam in the single sheet feeder. The above instructions did fix it, but its very sensitive to how the paper is aligned.
If like me you have a LCD screen with manual RGB settings (such as a DELL2408 / DELL2407) don’t follow the Spyder 3 Pro instructions (minimal as they are) since you will waste a lot of time and negate the real benefits of the Sypder tool.
After contacting datacolor support they said to do the following:
In the Spyder3Pro software, GO > Edit Display Information … >
Turn off the RGB control (basically tell the software you don’t have any control over the color of the monitor)
Then perform a full Calibration. Using this method, the software sets the profile for the monitor and automatically selects a pretty reasonable calibration. I still have one monitor with a very slight red tint (common issue reported by many users). Next time I will stick with an Apple monitor.
